I've been using the new UI for a few hours, and unlike most people on here at the moment, am generally happy with the changes. However, there are small issues which have been bugging me a lot recently, so i'm going to dump it all here, and add to it if i notice anything. Of course though, I play on a 28" iMac, so I guess my experience will be different to the average player anyway! I've added my ideal solutions, too :3

Key:
P: Problem
Numbers: Solutions

Suggestions:
P: The Chatbox is too high, especially feeling so in Haven.
1: Move the chatbox down when the bottom UI is hidden
2: Give an option to move all lower UI elements to the right-hand side

P: The Shield HP bar looks... Awful
1: It needs some kind of texturing, I'm sure it wouldn't take long in Photoshop or something to find something that works.

P: You can't see your Crowns and Energy all the time
1: Change it, seriously. Seeing your crowns is really rewarding, and I look at it a LOT. Pressing the Arsenal button is a pain.

P: The relation colour-coding is confusing in Lockdown, and looks a little funny.
1: Override said colour-coding in Lockdown and Blast Network, so all of the name, title ETC are the team colour.

P: Its not immediately obvious when the UI is Locked
1: When you try and click on a UI element when it's locked, display a message that it is, with the option to never show it again.

P: The animation to the Esc screen lags slower computers
1: Can we have an option to turn it off?

P: Some people detest the new layout
1: Add a Classic UI option
2: Carry on finding out what people want, and adapting it!

Edit: Please keep feedback in the release discussion thread. Thanks!
