The possibility to move items up or down in all the lists would be great.
There are currently no plans to allow items to be rearranged in all of the lists.
However, you can use the “focus” button to move an item to the top of your Soon list. Just tap the round bullet icon to the left of the task name in the list. (Or on older versions, tap the item to open the command bar and then tap the “focus” button.)
