If your tasks are in a note, you can sort them manually from the desktop or web app. You can also set a default note to collect your tasks you do not add to a specific note. Once in the note, you can sort manually, but ONLY on desktop, at least from my experience. I am on a macbook pro and can sort FROM THE NOTE ITSELF (not the task list), but then trying the same on my Apple SE with no luck. Any ideas on how to do the manual sort of tasks in the note while using a mobile device?
