Export Mode Simple Requests

Hi, I have a couple of suggestions for those of us who use RB in Export Mode Only:

Show/Hide Tracks Of A Playlist
-----------------------------------------
Can we have an option to see more than just the artwork and the track title ? Add the BPM/other columns for example? 

Column Chooser
-----------------------
Can this open in a new window, so we can choose columns we want to see/hide all in one go, instead of having to right click on the column and select one at a time.

Move tracks from Playlist to another Playlist
----------------------------------------------------------
Having the option to move, rather than copy a track to another playlist would be great. SHIFT+mouse drag for example.

Thanks
