I don't know that adding things that already exist in other material is a good thing (or, ya know, legal), but some more bard options would be fun. Something mentioned on the bard thread was a class feature that allowed bards to apply CHA mod instead of STR mod on combat maneuvers (I have a bard who wields a bladed sash in my game, and I think CHA would work just as well as dex to hit with it). I could see this being made into a feat as well (and it wouldn't allow too much ability swapping in the way that I fear snowflake wardance would).
