It's very nice to see this in the tags, and it would be useful to see in the "Files will be named like this:" before and after sections of the file naming script editor too.

As a side suggestion for this and the tag one (not too sure about this) a separate diff (but in the same field) for the file name and folders? For example bandcamp downloads are like "Artist - Album/Artist - Album - track# title.ext" and the diff showed "Artist - Album" being removed from the folder even though it's being removed from the file. A bit nit-picky maybe, I'd be fine with it staying how it is too.
