Include more metadata sorting options on playlists/whole collection
Last request would be the inclusion of more sorting options applied to tracks' metadata (cumulative sorting capabilities).
Example: Sort all tracks in my entire collection/specific playlist by Artist AND by Track Name AND by Year (and so on...) just by clicking on each column (software already has implemented this simple behavior).
The ideal thing would be to be able to sort all available/visible columns. If not possible, sorting, at least, by two/three columns would be great.
Thank you in advance,
