It's a lot of steps to delete a to-do:
Expand the To-do
Open the overflow menu
Select "Delete"
Confirm in the pop-up
This is a click-heavy workflow for a task that requires double (or triple) confirmation: the delete button is not in an easily accessible location, so the pop-up seems a bit over-the-top and really slows down a workflow.
IMO, either of the following would work:
Add a trash can icon to to-dos when collapsed
When clicked, show the pop-up to confirm (since this location is easily accessible)
Keep delete where it is, but remove the extra prompt
