Draft mode when planning in board
When you are working in a board, you may want to move many things around (issues, lists, labels, etc.) but commit all the changes at once and not before. Because you might make many changes along the way like moving an issue back and forth from the same list multiple times. And so you don’t want that messy transient interaction in the system note history because it’s not relevant.
Some draft mode so that you can stage your changes before committing them en masse. This could get complicated quickly with all the possibilities of things changing in a board and also the problems of real-time updates. So a first iteration can focus just on moving issues between lists.
