this is something I want to do eventually, but I don't think it's viable for the current generated static version of the site

I plan to make a SPA with a backend in the future which would have dynamic niceties, such as a proper search, hiding of irrelevant namespaces, stacktrace deobfuscation, possibly viewing Yarn's Javadoc comments and so on
