Let's avoid the old mode of answer. Agreed, implementing redo and  
undo efficiently is not an easy task. However, Ben's comment was  
adequate. This happened to me several times. Not because I  
intentionally pressed delete. Because I was within the property  
palette and press delete to erase some text... and it rather erased  
the control.

That's one of the reason I systematically use STS/MLX excellent  
editor. <http://www.sonsothunder.com/devres/revolution/downloads/

That way, my script gets preserved even if I accidentally delete a  
control on screen (provided I was editing it, of course). And I can  
have a huge number of undo/redo under textmate (I am on a mac).
