Description from store
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.
