If in a single task, to delete it there is a trashcan icon and when you hover over the icon, it says "delete task." Simple. Obvious. Good.

But in mult-select tool, the icon looks different (looks more like a weird house), and when you hover over it it says "remove task." Non-intuitive. Not good.

The task-specific "delete" & garbage can is the better of the two. But most important is that the same action should have same icon & wording.
