What I mean is that if someone wants a human model, skin, or icon they chose Human and only human resorces show up. useful if you want only to get human, orc etc resorces and still have a fast loading eg you might want to look at all human only models
the list might be: =Race= All Human Orc Undead Night Elf creep
skins are already split into various categories Otherwise i get your point, and i think it could be useful. Easier for newcommers to find what they seek.
