Code search is the one bit Id like to see improved. Just hire someone who worked for Google and copy their internal code search. (Preview available here: https://source.chromium.org/ https://source.chromium.org/) Technical caveat: To work effectively, it needs to be able to compile (parse into an AST) the code, which for many GitHub projects is challenging. I'd bet they could easily get to 80% compilation rate though and then use dumb text search on the rest.
