Thank you Ghostcut. Nice to see another person chime in.
But here's the problem with doing this in general terms - what do you do with something like the podrace? No one is cutting the whole thing out. And the changes are so varied throughout the whole thing that there is no real way to categorize what has been removed between different edits without getting a lot more specific. And once you do that, you're kind of back to the specific manner of listing items I originally suggested.
The problem here, as I see it, is how specific do you get? Generalization won't take us very far, I fear. And the more specific we are, the more useful the spreadsheet will be (I think), but the longer it will get, to the point where you might as well just use the cutlist script.
I'm not sure I see a way to crack this nut.
