I get it, trying to cut down on a thousand different names for things that do the same thing. But, in this case, it's clunky and confusing. When you see the same word that many times it becomes background noise, and that noise is disrupting.
Class/Skill/General feats already do different things, why not give each thing a unique name.
Unfortunately, I couldn't come up with any good suggestions, so there's that. I guess Class Abilities, but that doesn't quite have the tone of choice. Skill Talents, maybe.
