Layout Saver

I was thinking of maybe a Room Layout Saver function which basically allows you to revert back to an old layout. ;o

All you had to do was place all the furniture you used for the layout in the room (a list would show you what you're missing if anything) and you can have an option of 4 previous layouts you've saved.

This might be useful for avoiding closing a room if it were to be trashed (you could revert back to your layout) or simply if you just want to bring back an old design. ;o

Like any idea, flaws will be discovered. I can't think of any flaws, but maybe you can post some if you find any. 8D
