I was thinking about powers that showed up during or after the NK arc and the only one I could think of would be the telepathy. I'm sure it would kick in much more strongly earlier had he lost his sight longer than he did.
Well, there was the whole "Clark wakes up and knows Lois is in danger" scene in HIWTHI. But I just always assumed that the telepathy thing only worked Kryptonian to Kryptonian.
