This would be a late-development suggestion, but one thing I love about Swtor is that there is a clock there timed to my local region so that I know what time it as and know if I have enough time to play another few missions, grind enemies for play some space battles before work, bed or going out to somewhere important.

This will mean you'll need the clock set up in whatever timezone the different servers are in, but I find this as a really handy feature and well worth the time to invest in.

Having a clock displayed somewhere in the UI (most common in minimap "frame") is essentially a standard feature nowadays in MMORPG's. If it's not configurable then it should default to displaying the same time as the computer it runs on, otherwise I would advocate to being able to switch between local and server time.
