imo you need to start giving uservoice some attention. it's not enought to open up the uservoice "forum" and allow everyone to dump their (frankly often silly ideas) onto that platform.
you as admins need to step up and weed through all of this. give your opinion on what's on the roadmap and what stuff is never gonna happen. start rejecting. there's 21 pages of suggestions right now which seems like way too much.
