There’s been a couple of feedback responses from Blizzard to testers today including news that a real time clock is being added to the UI mini-map.
Also Blizzard is looking at some of the chat issues when salvaging and the colour of messages that appear in-game:
Addressing Blacksmithing messages being the same as player chat.
All simple small bugs that make a big difference to the interface experience that will also be easy to fix. A good example of getting the polish right. The addition of a clock is a nice touch although not essential. Not sure I want to keep seeing reminders about how long I have been playing, always shocked me in WoW when I kept checking it ;).
