Add <Category> to Highlighting Criteria fields dropdown list

[emmaoninternet]

This may actually be more of a bug report than a wishlist thing, but it's low priority either way.

I juuuuust discovered what data is actually in the <Category> field (Music, Inbox, Audiobooks, etc) and was going to clean up a couple of my highlighting rules that use path > contains to designate my Inbox/Library files instead, but discovered that <Category> is not actually available from the Highlighting Criteria Editor field dropdown list:
   

I'm guessing this might be due to the highlighting and auto-playlist rules sharing the same "pool" of available fields, since <Category> is also reasonably omitted from the Auto-Playlist criteria list, given that 'music track source' is already designated separately:
   

I haven't noticed the <Category> field being absent from any other field-selection thingies (e.g., virtual tag/renaming/whateva <field> pickers) and was also able to successfully create and use a virtual tag consisting of just <Category> to exactly the intended effect - which is why I'm not sure if this is more a "fix" than "feature" request.

Again, not at all pressing, but let me know if you need any more details - thanks!

J/k, found another field dropdown list "missing" <Category>, although not in MusicBee, per se, but the Additional Tagging Tools plugin Advanced Search & Replace editor:
   
    (<Category.test> is my virtual tag that is just <Category>)

Dunno what the source of the <fields> "pool" used for that dropdown is, but I can x-post this info in the Add'l Tagging Tools plugin thread if more appropriate.
