Yeah the recent changes are annoying. I have a ssd named g: and hard drives named E: and F:. It was defaulting to the beta installation I had on drive E: every time. Even after deleting folder on E it still acts like no game is installed because it looks for E before finding the game on G. It auto switches now which is nice. But I've noticed that it doesn't remember sorting between sessions.
They really did mess up something that wasn't broken. And for those saying its twitch and they are not about addon's. Well it has been part of the app for several games. It is as much of the addon as streaming. The game store and addon's are a part of twitch as anything else.
