Well I havent been working on the GUI in a while, so I have no changes to show.
I also haven't done any work towards getting it working in-game other than a few experiments with the buddy window. I'm not so sure it would be a good idea to invest efforts into a GUI mod this early in the games development. Every update could easily break it's functionality and who knows how much the GUI will change in the future.
Im glad to hear the current GUI is being improved on, though I will mention I have nothing to do with it, atleast not directly. I did see in the 0.4 Changelog:
A new Group Window, it's more minimalistic and displays race icons.
and can hope I had some help in inspiring that addition.
I can't wait to see what the new version is like (hopefully the mac client will shortly follow), and I do plan to continue working on this concept.
