main mods i'm waiting for that i think will come eventually:
smooth skin mod for Tieflings (so you can have horns, nails and a tail without the weird bumpy skin!
more druid forms! (dragon?! :D)
new half races! (half tieflings like Doric from the D&D movie?)


and a mod i'd like which don't expect to see is a mod that gives us a spell to transform NPCs into player (complete with the players current armour)
mostly for making cinematics, so most people wouldn't be interested in it, i don't think it will ever happen :P
we have mods to turn NPCs into different NPCs and turn the player into NPCs, but no mod to make NPCs look like the player!
