I also really like the look of Android Cross compared to the iOS & Desktop versions. I've always liked blue and orange together (complimentary colors!), and I think the look of the Android version is a little cleaner looking then the iOS app.
I would like it if you could choose the deck color for the desktop version. I use white and orange control vinyl for my A & B decks and it would be pretty cool if I could match the deck colors to my vinyl
Though I don't really know how hard that would be to implement and as it's only a cosmetic change isn't super important to me.
