So I'm thinking it would be nice to be able to edit a current base and, if it doesn't work be able to move back to the last saved base layout that you had. I've modified my base many times trying a new idea, but in the end would have liked to move back to the base layout I had before. Although most of us might remember that layout and be able to duplicate it, it would be nice to be able to simply revert to the last format with the push of a button.
