Well, I am not a graphics designer... At this stage I am still concentrating on the features, rather than the interface and design...
BTW, you should be able to change most of the graphics/fonts, etc... as long as you keep the right proportions...
gmdl suggestions should be forwarded to in7ane, as he is the creator of this software.
Personally, I think that gmdl is not that buggy, but rather has some learning curve - I wish someone would write a tutorial on how to use it... and what caveats to watch for...
