In-game play timer.

The Weekly Missions track the amount of time you play, not counting time spent in the lobby. That's a very useful feature but it's essentially only available on Monday. I'd like to see that kind of feature added as a permanent fixture on the UI or logout menu. It shouldn't have any rewards attached to it. It would just serve as a general tracker when the website event page fails to update, or simply doesn't have a tracker for a specific event.
