First of all, I'd like to say that the project is really great, I was thinking of building something like this. I went through several implementations but yours is the closest implementation to the one I wanted.
Keeping that in mind, what are your thoughts on making an extension that would add a component in the github repo itself? It would take time off from going to the site to individually search through repos, and be a nice addition where you could add a list according to descending similarity score for the top "k" results.
