Hello everyone! First I want to say that this game is awesome! I only joined 2 days ago and I am addicted already. However I have a few suggestions that I hope will be taken into considiration.
1- The ability to see people’s preferred language. (The language they used to solve most of the challenges.)
2- The ability to see your rank within the people who have the same preferred language.
3- The ability to see your rank within the players from your country (Currently it shows your golbal rank and you need to count the people above you.)
4- Add country ranking.
5- Add language ranking.
6- The ability to see the optimal code of any challenge after 100% completion.
I might add more suggestions if I think about anything else.
