Haha, that's funny, I'm literally working on it right now. And yes, a big update is planned, I'm just waiting for a critical bug fix to reach some of the main Mbin servers (one of the api endpoints completely deletes the user when used, which is definitely not supposed to happen).
An AMOLED theme was not on my list, but it's probably something I could do before the update. Would that just be a theme with a completely black background?
