Anyway the thing to it is if you accidentally destroy a brick, instead of rebuilding it you can undo the destroyed brick(s) with a certain key-bind of course.
you know you can ctrl+z to undo some thing other than bricks, would be nice if it was made or someone can make it.
I looked to see if anyone had made this, I don't think anyone has, if someone has please tell me the name or giving a direct link would be nice.
