Thanks, @Marie; “Make a Subtask of…” is a great addition!
But the placement of “Add to Project” within the “Move Task” menu is not right because the task is not itself moving at all.
I think either:
- “Add to Project” should be in the top-level menu, or
- Change the sub-menu name from “Move Task” to something a little more broad (“Reorganize Task >” maybe?); that would allow keeping “Add to Project” within the sub-menu, and now you could also include “Duplicate Task…” in the sub-menu as well.
