Create sort rules for individual playlists (both ordinary and Intelligent)

 Left click on a playlist.

Then Right click on Sorting rules options.

Then the user creates various sort rules.     say  Rule 1 by Genre

Rule 2   by bpm or some other

Something similar to the way the intelligent playlists rules are created in the first place.

I should think a maximum of 3 rules should be more than enough for most ppl.
