If I have useful stuff in a cell, but I need to edit it, and I'm afraid I  
might delete things I need, add things I don't need, change things that  
are already perfect... well...

I just copy the cell and paste it above or below, and I edit the copy,  
leaving the original alone!

Or, if there's a lot of editing going on, I copy/save the whole file!

Later, when I've gotten moronic and made a mistake (it happens!), the  
original is still there. I can copy/paste between the two versions until  
I'm happy, the code's happy, and nobody else cares!

That's WAY more flexible than multiple undo could ever be, isn't it??

I mean, what if the change three layers back was bad, but the last TWO  
changes were great (and time-consuming)? How can undo help with that? How  
can I even keep track of which changes were good and which were bad, with  
undo? I can't!

WRI already provided copy, cut, paste, color-codes for missing brackets  
and undefined symbols, automatic structure-based indentation... haven't  
they done enough?

Really, at some point, you gotta wonder... could it BE any sweeter than  
this?
