The forums will be added back in, in the coming weeks. Not too sure when though, I have exams at the end of the month.
I didn't have enough time to implement them before this update, which I promised to release on Sep 30. I couldn't quite meet that deadline so I just uploaded the APKs here for a sort of unofficial release, until today.
As for favorite manga, I'll add that back in tomorrow.
Edit: actually, tomorrow night I have a test, so maybe the day after
