Due Date Widget
Select one or more track groups, then use Due Date to set or clear their due-date value. The widget shows the first selected due date, or Mixed dates when the selection differs, and applies the change optimistically to every selected track group.
Failure-safe updates
Section titled “Failure-safe updates”The update requires at least one selected track group and a valid access token. If any request fails, the widget restores every affected local value and shows an error rather than leaving a partial result. On success it emits a track-group update so other current surfaces can refresh.
