DISCLAIMER: I am making this thread as part of my own personal interest, not as a representative of Intrepid Studios.
Intrepid have said that the UI in Ashes will be fully customisable but they haven't said yet what exactly you can do with it. So, I'd like to know what kind of customisation options YOU would like to see.
I'm going to hold off on stating my own opinions until a bit later because I'm curious to know what the other community members think.
