Google Task SidePanel

Open Google Tasks in Chrome’s side panel anywhere you browse. The extension simply embeds https://tasks.google.com/ in an iframe—host permission is required only to show the page and never touches your data. Toggle the panel with ⌘ Shift Y (macOS) or Ctrl Shift Y (Win/Linux); you can change this shortcut in the Options page. Fully open-source: github.com/yumebayashi/tasks-extension
