Dashboards have a wonderful functionality to be able to drag and drop tasks between widgets to change statuses. Unfortunately, it only works for status differences.
I would like to be able to drag and drop between two widgets that are configured the same with only one difference. I.E. they both are looking at active tasks in the Personal folder but one has a filter for a custom field being checked and the other has a filter for the custom field being unchecked. Or they both are looking at active tasks assigned to the current user but one is filtered to Folder A and the other is filtered to Folder B.
In those two examples dragging tasks between the two widgets would toggle the custom field or move the task between the two folders, respectively.
Of course there are some filters that wouldn't work like Last Modified Date, Created Date, etc., but filters on fields that can be changed would be wonderful candidates for drag-n-drop changes.
