[Random Talking Bush]

I still think the sheets themselves should specify whether it was from a prototype or not just for archiving's sake, but that can be physically on the sheet.

I only say that because sometimes on a prototype there's things that are literally not on the final copy, not just inaccessible. I know that's splitting hairs, but it also prevents confusion. The confusion would only arise in very specific situations though.

That's why I thought "Unused" was a pretty good catch-all. It could be beta, prototype, or something dummied out. We just know it's unused.

But it's not exactly "Unused" if it was used in an earlier version.

I still say we should keep the beta/prototype stuff separate from the actual unused content, where applicable.
