don't know if everyone knows about this, but you can dump some of those files you mentioned into a dot github directory to keep them out of the repo root.
Yeah, in my example I used a "docs" directory supported by Github since Geany already has that, and there's already miscellaneous documents in there.
Multiple issue templates are supported as well
That's cool! We could probably have at least two for "bugs" and "feature requests" or whatever. I'll have to try it out sometime.
