@Sophivorus I'm currently working to match the functionality that exists in the core watchlist, does this exist there? I agree it would b useful, but I'm not really sure how to approach it - even just knowing that two edits are tagged as reverted and a revert (undo/rollback/manual revert) isn't necessarily enough if there are more than those two edits to show

I believe this functionality doesn't exist in the core watchlist. The closest thing is that little number showing the diff in bytes, that when adds up to zero, usually means vandalism-revert. If you implement the byte-count diff as in the core watchlist, then maybe it wouldn't be too difficult to add a filter to the settings to "Hide groups of changes by two or more users that add up to zero-bytes". Notice that changing a single character for another, or a word for another of the same length results in a zero-byte diff, so the filter should probably match groups of changes by two or more users that add up to zero-bytes to minimize the chances of overlooking vandalism. Then the only vandalism that would be overlooked would be when some vandal deletes some content, and then some other user adds some content of exactly the same number of bytes. This is so unlikely that chances are the only way it'd happen would be by some coordinated attack, which would make little sense since other users not using the global watchlist or this filter would easily spot it.
