Feature Request - Tag Area & Playlists

I am using tags a hell of a lot to organise my tracks, and I am finding that I am having to scroll more and more and more as I add more tags.

Could you please look at the ability to add the following to a future release of RB please:

• The ability to allow more than 4 tag sections
• The ability to collapse sections

I use tagging so much so that I can create intelligent playlists, so I can quickly find tracks within a certain genre which have specific elements, energy or for certain times of the set.
For Tech House I currently have 27 intelligent playlists and growing, and I currently have to create each filter manually with is extremely onerous. 

Could the ability copy a playlist to another playlist be added please?
