Excellent news:) Best of luck! There certainly are some great-looking ensembles out there…but also plenty, too, that have huge download numbers and sky-high ratings that don't use any added graphics.
IMO, better docs/help/comments and plenty of demo snaps are the most important "extra" features. I've been loving Reaktor and the UL for over 20 years now, written tutorials and
made how-videos for various ensembles, but there's STILL a huge number of UL uploads that I can't figure out how to do anything—or anything interesting—with, including several of the just uploaded competition entries. Less is NOT more when it comes to usability!
This is definitely something I'd be happy to help with, in any way, like beta-testing, snap-making, even tutorial-video making. Wish I could also offer graphics help!
