Link to gh.com repo/user from .io page.

There’s a surprising number of persons whom have a project page, but it doesn’t link to the repo.

When at username.github.io/projectname, link to github.com/username/projectname.

Implementation is not straightforward.
First, I’d be against modifying the .io page. The add-on has toolbar presence (currently opens gh.com when opened). It could be used to instead open the repo/user page.

projectname isn’t always available on github.com. Checking, if it’s 404 should direct the user to github.com/username instead. Not sure, what’s the best way to check, and what to do, when checking fails/isn’t available.

I remember seeing some extensions that do this, but they are really old. Perhaps still work, I don’t know.

But I have a userscript for this use case: https://github.com/kidonng/cherry/blob/master/scripts/README.md#pages-source

This is tough because it requires UI either on the page (👎) or as a browser icon context menu (so undiscoverable) + it requires adding a *.github.io permission, which disables the extension for everyone.

I don’t think it’s worth it. The same could be achieved by manually selecting .io/ in the URL bar, pressing <kbd>space</kbd> and then <kbd>enter</kbd>
