Enable Undo mode in moving a group of todos

While moving a list of grouped todos across lists, it’s easy to make mistakes and land the group in an unintended list. If the grouped items are substantial, manually moving them back is very hard.

Enabling undo mode will solve this.

I generally agree here. Let me see if it’s relatively easy to incorporate into our undo (if more complicated it will be in roadmap), and at the least I think we could/should probably increase the window before it springloads you into a list to drop off as well, feels a tad trigger happy right now.
