Seems to be a bug in the stopwatch feature. Absolute waste of time here.

I installed this on Chrome, but I don't see the icon in my extension field near the top of the browser, nor the list of extensions. If I can't use it, I must remove it!.... ITS OF NO USE TO ME :(

None of the alarms I set went off with sound alerts. I double checked my volume and could clearly hear the alarm sound when choosing from the options, but when it comes time for an alarm to go off all I get is a pop up window. Not very helpful

I was looking for a stop watch that allows a pop-out window, but it is a shame that the stop watch, the only feature I needed, seems to be stuck with "Stop" and "Reset" as the only options, with no response to my input

The only thing about it is that when you start a stopwatch for something for more than a few minutes and you close the popup, the stopwatch doesn't even work anymore. I've tried to reinstall it, and it still doesn't work.

When I close the popup it and open it again it won't start.
