There have been a lot of other UI changes with Update 2 so far, mostly stemming from the Character Panel change and the LI revamp that is in the works. Here are some screenshots of the changes I’ve noticed so far.
New ^ Menu drop Downs — Under ‘Character’ you can see there are some new drop down submenus. This is because most of this is not accessible from the character panel anymore. This could be annoying when trying to look at Reputation.
The New Instances in the Instance Join Panel — as you can see, we’ve gotten some new instances! The top one is the raid, the next to are fellowships, and the bottom two are small fellowship. Note that you can’t access them from the IJ panel until you discover their actual location in-game.
