I would consider different name for "tree". It ain't obvious to me if it is tree graph for my git tree or tree of catalogue in source.

"Tree" in Git parlance has a pretty clear meaning that's basically synonymous with a directory.

OTOH, it is consistent with cgit.

Yes, my main inspiration is cgit. I mostly followed that and written in Go with some improved UI(which is what I was deliberately wanted to do).
