6.) Twitter no longer updates constantly. I'm sure this was done to save battery power in some way, but this is annoying. Now, I can't tell when I'm getting twitter mentions because the app itself doesn't update frequently enough. It would help if there were a setting to customize how often you want it to update, but there isn't even that. The twitter feed on your notification page will update, but it of course doesn't show your mentions, retweets, or DM's. .
