Is there a way to move a task from one list to another? I want to divide a list into two separate lists.
I had to think for a minute and then it hit me like Momma Cass stage diving. Quick Actions are what you want to use. Go into settings and create Quick Actions with a "Type" of "List", choosing the list you want to move tasks into. Create one for each target list. Now go into the list with all the tasks and use Bulk Actions to select tasks, and assign the new quick actions you created.
I think this will do what you want.
