Wow - somehow I managed to completely overlook the fact that there is an undo button. Could have saved me a lot of time! :p
I'm yet to use the undo button myself but thats more to do with the fact that I just prefer a full clear and start over when I go wrong :P
I think the undo button is necessary though. Mis-clicks are always possible. The color changes are not as necessary IMO. |
