um.... how bout a little engraving (looking like what I've got now) of a Chinese dragon that goes along the hot-bar!
That would be cool....or maybe you can make the hotbar the square symbol thats at the "output" of the crafting square right now and make the inventory another symbol, and make the armor a different symbol, and the crafting square a different symbol (a unique symbol for each "group").
and also some of the items don't really fit the symbol, and some (seeds) are not really visible. I don't know what you can do about that, aside from making the symbols lighter and simpler (maybe just a square with some variants), but I don't know how that would turn out. Maybe you should remove a row of "bricks" from the bottom of the hotbar, as some items encroach on the design.
Hopefully within the next three weeks. I've only got on more exam till I've finished this semester at collage
I'm mostly done with the terrain and I have the assets for finishing my GUI. I need to do allot of work on my Mobs. When I have about 80% of textures done, I'll probably release, then start working on alternate textures and a customiser.
