Well, I've always rather disliked both the default UI graphics and most if not all of the graphical mods made by the community.
So here's my initial mockup of what might become a full fledged mod, someday.
Now I realise that some (if not a lot) of what I've illustrated with this image might be impossible given the limitations of the VG UI system. Though since I'm not yet at all familiar with the detailed workings of the XML behind the UI nor it's limitations regarding graphical display.
So please, let me know what you think and how possible it might be to use specific elements of the design such as shadowing on text (non image based text).
