Description

Enhance your Google Calendar experience and boost your productivity with GCalPlus, the Chrome extension that adds powerful features to help you stay organized and efficient. GETTING STARTED: After installing GCalPlus, open Google Calendar in Chrome and click the GCalPlus icon in the Chrome navigation bar (top-right, next to your profile picture) to access its features. If you don’t see the icon, click the Extensions (puzzle piece) icon and pin GCalPlus for easy access. Some settings may require you to reload the page to take effect. For features that need access to your calendar or settings, click “Connect” to grant the necessary permissions. You can revoke these permissions at any time at https://myaccount.google.com/connections Having trouble? Try clicking “Disconnect” (top-left in the pop-out) and then “Connect” again allowing all the required permissions. ******* What can GCalPlus do? Options for the LOOK: "Expand the Month Grid" (previously “Show More Events in Month View”): with this option you'll see at least twice as many events per day in the 'Month' view, and the entire page will scroll. For this reason, the option "Disable Month Scrolling" (in the “Feel” tab) should also be enabled. "Highlight & Toggle Busy/Free": Connect GCalPlus to Google Calendar and enable this option to see at a glance on which days have events in your chosen calendars. This works in all month previews, not only the year view, and also adds a red/green button in event popups to quickly toggle events between Busy & Free. "Show More All Day Events In Week/Day Views": With this option you can display twice as many All Day events in the Weekly and Daily views. "Hide Invites On Shared Calendars": When you invite someone who has shared their calendar with you this hides the duplicate that you see on their calendar. "Hide Primary RSVPs for Secondary Calendar Events": When people RSVP to invitations on secondary calendars their RSVP shows on your primary calendar. This option hides the "duplicate" event. "Hide Images": use this to remove the illustrations automatically added for events with keywords in the title. "Sort All Day Events": All day events used to be grouped by calendar, then were listed alphabetically regardless of which calendar they were in... and now they are grouped by calendar again. Use this option to list all day events alphabetically again wherever possible. "Solid Tasks": Don't like the new faded Task colours? This restores them to full colour! Now ignores completed Tasks "Remove Task Circles": More room for Task titles without the 'timed' and 'completed' circles. "Large Dots, Small Numbers": This applies several custom styles to Google Calendar - compact day/week column headers and larger coloured bullets for timed events. "Hide Upgrade": Already got a Workspace account? This option hides the huge "Upgrade" button top-right. "Colour Timed Events / Timed Bars": These options allow you to change the way timed events are displayed in the Month and Year views. "Colour Timed Events" will set the text title colour to that of the calendar. "Timed Bars" will display timed events in the same way as "All Day" events, except with the time of the event. You can choose between dark and light title text, independently of the main colour scheme you use. These settings are not always applied instantly so please refresh the page if necessary. "Weekend Background": select a color for your weekends. Options for the "FEEL": “Disable Month Scrolling”: With this setting Google Calendar Plus will disable annoying month scrolling which allows you to use “Expand the Month Grid” to display more events per day in the Month View. "Use L/R Arrows": Why not use the usual left and right arrows instead of 'n' and 'p' for the next or previous day/week/month/year? "Expand Overlapping Timed Events": when you hover over timed events in the Week or Day view this option expands the event to full width, and brings it to the front for easier viewing. When using the "Alphabetical All Day Events" option this also allows you to see the full range of multi-day events. "Show Titles/Descriptions On Hover": When activated, this option will display a popup of the event title or description when you hover over events. Descriptions will be shown when they exist for all calendars selected in the Calendar Selector at the top of the GCalPlus window. For descriptions to be displayed GCalPlus must be connected to Google Calendar and at least one calendar selected. "Disable Clicks on Location": This prevents Maps from opening every time you click to copy/paste the location of an event. Click the Maps icon to the left of the location text if you still want to visit Maps for the event. “Create Events from Year Previews”. Click any day in the Year view to list the events on that day - with this option you'll also see a button labelled "Create Event" which allows you to immediately create a new event on that day. Use your browser "Back" button to return to Year View. “Multiple Copy”: Click the "Connect" icon top-left to allow GCalPlus to access your calendars then enable the option in the “Feel” tab and GCalPlus will add a new "Multiple Copy" button to every event pop-up. You can copy/duplicate events to any writable calendar directly from any view, and you can select whether to copy guests or not in the GCalPlus options. Copy events to the same date (duplicate the event), copy to a new date, or copy to multiple dates. Please note: repeat series will not be copied entirely, only the selected occurrence of the event will be copied. Please note: your system must use the same TimeZone setting as the Google Calendar for which you are copying events for the best results. "Change Calendar in Event Popups": This option allows you to select a new calendar for any event that you own directly in the event popup by simply choosing a new calendar in the drop-down list you see when clicking the calendar's name. When you select a new calendar the original event is immediately deleted, a new copy is created (with or without the original guests) and the popup closed so please be careful with this option - especially if the event in question has Guests. For safety, this option is only available for single (non-repeating) events. "First Time Zone": Select the first time zone to be displayed in every window where you can select time zones. No more endless scrolling to get to the ones you need! "Time Range": This option allows you to hide everything before and after specified times. ****** "Debug Mode": click 3 times very quickly on the "Dark mode" icon to toggle debug mode on/off. This will display debugging logs in the Chrome Dev Tools Console that can help me solve bugs. ***** Recent Changes: 3.0.13 Ignore completed Tasks, new "Hide Upgrade" option 3.0.12 Bugfix for reinitializeTooltips 3.0.11 Option for solid tasks & no task circles 3.0.10 Better border 3.0.9 Added "Today" border option, fixed "first TZ" 3.0.8 Fixed Busy/Free Toggle 3.0.7 Fixed copying events across DST boundaries for all time zones 3.0.6 Fixed copying events across DST boundaries for user's time zone 3.0.5 More aggressive window resize for "Expand the Month Grid" 3.0.4 New improved Busy/Free display shows busy, free or both - with a red/green button in event popups to switch quickly between busy & free. 3.0.3 "Hide Invites On Shared Calendars", "Hide Primary RSVPs for Secondary Calendar Events", "Change Calendar" directly in event popups, guest options for copy/moves and cache enhancements for better performance. 3.0.2 Multi-calendar support for all "Other Calendars", better calendar list, improved "multiple copy" window with new button in main event popup, other UI tweaks. 3.0.1 Bug fix for holiday calendars 3.0.0 This version is a major update featuring a brand new UI with “Look” and “Feel” tabs, dark mode to match Google Calendar’s new look, multi-calendar support for busy dates and descriptions that display when you hover over events, and “debug” mode to help you help me to fix bugs. This is a significant rewrite with many optimisations under the hood and a new tabbed display to allow more features to be added in the future. 2.1.3 Multi-calendar support for busy dates & hover for descriptions 2.1.1 Added option for "Minimum Time Zone" ***** GCalPlus is brought to you for free by GCalTools Power Tools for Google Calendar.

Trying to use this app as its functionality would be a great add to our workflows, but whenever I connect a calendar and click the extension to configure settings my google calendar refreshes and I am unable to configure anything

I use this extension purely for one reason, and that's the "Month's show busy dates from :" Option. This allows your little month view on the left side to highlight the days that you have an event or a task on (This also translates to highlighting the days in the YEARLY calender view) Every 2-3 months this function completely stops working and it's the most infuriating thing I can deal with as I jump through many, many hoops to remediate it. A few of these are : uninstall the extension, clear cache, unauthorise and re-authorise, uninstall google chrome and pray to the flying spaghetti monster in the sky. There is no definite solution and I can never recall what I did the last time to make it work, it suddenly just starts working again. (This includes disabling all other extension including any Dark mode options). Please fix this.

very disappointed. CAme to this extension to reduce the hours the calendar displays to show relevant time of day in greater detail, but the Day Start/End: function does not work at all.

Only thing that I wanted- To be able to see my events in the year view, as most of my events range from the 2 week, to 3 month size, for work scheduling, and this is not possible despite it saying it is in the description. So: only thing I need it for and it doesn't do it. haven't been able to find a way to do this yet.

This doesn't work at all unfortunately. I've authorised the extension and reloaded the page, but not of the options do anything. Looking in the console shows the following error when changing options in this extension "Error in response to storage.get: ReferenceError: $ is not defined"

Unable to enable features and developer not responding to request for help. Maybe I am doing something wrong, but would love to be able to benefit from his hard work, right now, not so happy with the program.

This extension isn't doing anything for me. every time i click it it just takes me to the chrome store as if I never installed it (but it is). Do I have to actually purchase?

I used to really like this extension (and will really like it again if this gets fixed!), but for the past few weeks, it's been preventing me from adding/modifying notifications to events, which is a crucial feature that I desperately need, so I'll have to keep it disabled until the issue is fixed. :(

I was looking for extension that show me marked events on Google Calendar in year view. This can do it but: only marked on red (no option to change size or color or no option on hover to display name of event - still talking on year view). The main bug is I need each time I open my Google calendar: reload and logon to GCalPlus (also plenty of logon pop ups shows on menu bar). This plugin is useless or too buggy.

Honestly, there's not many features that I really care about except the ability to hide inactive hours, but that apparently doesn't work. Even if it did, the two boxes doesn't allow me to hide hours 1am-8am for example. It just x am to x pm. I don't sleep 12 hours a day. "Titles on Hover" doesn't even work for events that are combined so you're basically only showing the title on single events where you can already see the title. What's here isn't useful or doesn't work. I'm really disappointed.

Would love to give this 5 stars, but it is giving the dreaded "Sign in with Google temporarily disabled for this app", therefore it doesn't work. If it gets fixed, please update us. I'd love to try it out. Seems exactly what I'd need when using multiple calendars with a ton of events. But until this is fixed, it isn't useful at all.

Worked perfectly fine for a while, but now the Multiple Copy function doesn't work for me anymore; it only copies the event for the same day instead of me being able to pick the dates to copy to...

Does not work properly. I attempted to add an event to 3 upcoming days in a different month. It added the event to the wrong days and only put the event on 2 days. Sure was hoping this would work.

I've twice had to unistall and reinstall because it randomly makes my month view have a ton of white space in the boxes, and for me that defeats the purpose of month view because I can't see the whole month at once on my screen - I have to scroll down to see anything beyond two weeks. There are some things I love about the app, but this is very frustrating.

There's no setting for day start/end for me. Where do I find this setting?

UPDATE. Prevents Mouse Wheel Scrolling Month to Month I guess been like it for a while & put up with it but annoying now, Perhaps an update has/will fix but I use another ext. that does what I want Looks really good. Wish list : Change background colour of weekends Really highlight current day, not just the OEM blue dot Perhaps too much info. but would love option to display the Details on hover, is handy the full title but this would be a great addition. nice but not essential change background colour overall. (I see other ext's to do some of these things but not sure want to merge too many)

Pretty good for the most part. But today I noticed it's now hiding Out-Of-Office events - as in they disappear completely from the calendar. But the events still exist because they show up when I turn the extension off. Pretty annoying. I need to see them to ensure that people will know I'm out that day.

Night time hours can not be hidden. The morning one works just fine.

There's a very big bug in "More Month Events". We have to update the extension every time for it to run correctly. This is very unpleasant.

In the year view, the highlighted days are on the wrong days. I made sure I had the same calendar selected in the extension and the list. It shifted events by one day for some reason.

★★★☆☆2021-12-09
Daniel McCammon

added extension to limit the time range in calendar, and technically works, but does not enlarge the vertical space at all and instead just 'crops' the standard display, which doesn't end up helping all that much (both ends up with empty vertical space)

Well i didn't see any changes even after I've authorized the extension, especially the Multiple Copy didn't show up at all, it's the feature I desperately need :(

Google Calendar still displaying "+More" in Month Views and not expanding.

★★★☆☆2020-02-18
Robert Andrews

It's pretty good. I primarily got it for its ability to constrain the time range viewed in the viewport. Whilst it successfully allows me to view, say, only 5am to 11pm, I think the script may benefit from nevertheless expanding the height of what IS viewed to the full height of the browser viewport. On my iMac screen, this just leaves a lot of white space, whereas what I hoped for was to EXPAND focus on key hours.

Is there a way of making the height of the row until is needed, so it will show all events but no extra space? Thanks

This app seems like it could be really useful and there has obviously been a lot of work put into it! However, when I try to show more events in month view, it stretches the days out vertically and lets me scroll (which is fine), but then doesn't actually show more than 2 events per day (it just shows "+2 more" like the page without the extension does). Being able to see many events per day in monthly mode is why I downloaded this extension, so this is a major issue for me. I did refresh the page so that may have caused the issue, but I reset it manually and it still isn't working. How could I fix this? I really think this would be a gem of an app if not for this issue.

I really wanted to alphabetize the all-day events when viewing multiple calendars at once. I have 2 vacation rental properties so I'd like to see when each is available. So "Apple St available" or "Apple St booked" would always show above "Banana St available" or "Banana St booked". So in theory it should work and always maintain the #1 and #2 rows at the top of each day. But it winds up overlapping timed events instead of the timed events showing below and actually leaves a blank row. Close, but no cigar. :(

Update: *Oh dear, multiple copy has fallen over! Hopefully you'll have a fix v. soon... -2 stars temporarily...* Finally you have solved my biggest frustration with Google calendars - not being able to copy an event multiple times without it fitting into a regular recurring pattern! I used to have to do this on my phone using Business Calendar but this is great, thank you!
