We've been quiet for a while as we continue to work on the game. The new UI code is going well, but it will be a while before screenshots
Really there are two targets, Desktop and Tablet. Each get a different UI scheme. Mac and PC, only major difference is right mouse button.
I'd feel very silly if we did all the UI rework and just released the same old UI functionality in #bgee. ;-)
Custom button mapping will be in game.
The desktop is getting a UI overhaul. How far Cam's data driven UI lets us change things is coming clear. Char gen is all data-driven now.
