My thoughts:

1. I like the idea of a real-time clock, but the main screen doesn't seem like a fit place to put it. The far right tab would be more of the place for a quick check on the time. A clock would be a great idea.

2. There is a battery bar in the far right tab of the character menu. It's a great help and is accurate.

3. I don't think it would be very good to have a person jump to the beginning of the level each time their is a call or an interruption. Move back a little bit and send the team a quick message saying "brb" or "afk" and you should be fine.

4. I would like to see boss stats, not on or above the boss himself/herself, but on the leaderboards would be a fun place to see which boss kills most and dies most.

5. Push notifications would be helpful. Mailboxes have been talked about in the forums before (I'm unsure of it it's being implimented), but that would be an ideal place as well.
