Undo/Redo Button
Desperately need undo and re-do buttons. A complicated budget can get overwhelming to manage if you've made mistakes and can't figure out how to quickly correct them. Maybe add an "edit history" as well, if it's simple and easy to look at.

I'm going to mark this as Done without adding it to iOS. You can ctrl+z (cmd+z) on web to undo or redo changes to the budget. On iOS, it takes a bit more to make changes so you have less of a chance to make a mistake. And for the scenario where there is a mistake, I'm going to add history to see what you changed. You won't be able to undo it, but you can see that you assigned $x to a category and can make a change manually.
