Amazing work! Well done! I want to contribute to this project, if I find what others may benefit from. So far I'm deeply impressed.
The only thing that annoys me to no end is that, whenever I enter something in the Search input field, I get this browser's pop-up dialog prompting me to save the password. I think that's probably because there are authentication input fields, like "username" and "password", in the same form. I see this page doesn't use form at all, so the whole document becomes a form, and the username/password fields trigger this pop-up on submit.
Sorry for polluting develop branch with my PRs, it took me an effort to figure out the github error I kept getting on app.contribute, all superalgos reported was the following
