Browsing multiple palettes

I find the way palette's work not very fluent.  in minimized mode you can toggle 3 views of 4 preset possibilities.  This somehow limits your options to 4.  If you have many playlists (like me) it would be nice to add additional palettes when enabling them. Having 3 rows of palettes visible (or 2 or one, depending on your choices).

When displaying the playlists in the palette, of course then only the main selected palette is ok.
