Just to expand on my last idea regarding RealSets...

Just a slight improvement to the way you can change RealStyles in the middle of a song would be huge I think. So, currently you have to pop up an obscure window and select the style change and it is not really indicated in the song so doing it once is complicated and doing it multiple times would be way too complicated to even attempt.

So, how about making it much easier to change styles on any bar? And then make RealSets where PG's experts group together cool RealStyles that might work together? And give us the option to change/create RealSets in the same way we can change/create RealStyles?
