It would be really nice to be able to view progress in all puzzles per language. I initially solved several of the puzzles in a few languages, but I am not sure which puzzles I completed with which language and might want to go back and complete them for different achievements. It would also be helpful when trying to learn a new language so I could keep track of how far I have made it with it.
Does this already exist somewhere I have not noticed or do other people feel this would be useful?
