I put the NWN2 icons on, and I like them a lot, but, it will take a bit of getting used to. And since I play on 4 different computers/OS installations, I really have to put it on all 4 or it will be totally confusing. Luckily only one of my characters casts spells.
I wish we could have the spells and feats from NWN2 as well lol
