Click the "..." and Copy Task. It will generate the checklist again without anything checked, then just mark the old as complete.

You'd need some system to mark when one list ends and the next begins, KanBan just treats them as individual tasks.

> even basic stuff like re-arranging your list.

All of them let you re-arrange your list. Is this a mobile specific issue?

Everything in my comment was describing Planner. You cannot re-arrange checklists on a task in Planner on mobile. And I'm not clear if you were describing Planner in your comment, but I just tested the workflow described and it results in a second copy of my task with the same checklist items checked.
