He also copied the vortex and Kisame's water shark jutsu. Maybe others, but from what i remember, that's allDidn't he only ever copy the water dragon jutsu?
Kakashi's nickname is the copy ninja and is well-known over the world for that, but apart from the fight against Zabuza and against Kisame in part1, Kishi never used his copy ability anymore. What's the importance of a nickname if you're not even able to prove it? Do you think that Kishi wanted to limit the functionality of his sharingan on purpose? Or is it plot?
