It will be priced very competitively, as it’s a personal project and I do not need to pay anyone else ;) Nova’s model before it’s bought over was great. i still recall being part of those who paid $0.10 for it. The Google group is how Google currently handles closed beta sign-ups, not very intuitive, I agree.
Great suggestion on the “wizard”/ guide on first launch. The launcher starts a bit empty otherwise.
As for the app sorting, is there a reason why you prefer a permanent sort choice (by date)?
App shortcuts are definitely on my to-dos, and they will be supported as swipe/ gesture actions as well.
