Hover a comment to Edit or Delete it — editing uses the same editor as the task description, Cmd/Ctrl + Enter saves, Escape cancels, and edited comments are marked "(edited)".

Links in comments unfurl as cards below the text.

The new task dialog has a due date picker (Ctrl + D, or Alt + D on Windows and Linux), and unset properties shrink to icons.

G I goes to the Inbox and G S to Tasks, and the shortcuts sheet now lists every G shortcut under Go To.

Task lists can be ordered by status.

Recently Viewed now keeps the 50 most recent items.
