It would be nice if users could create their own skins for the mixer. Sure it's only cosmetic, but a degree of individuality would be good.

I was able to tinker with skinning a bit in RB 2011. It became more problematic in RB 2012.5
Hopefully they consider this suggestion seriously. I think user support would make skins a cool feature. I know I'd be willing to share whatever I came up with and I'm sure others would too; when it was working in RB I had other members send me what they had created. It was kinda fun making it 'look' however you thought would be cool. The functionality and layout was the same, but it felt a little different. I'm not a good graphics guy, but a bet some PGMusic members are!
