So now, I want to figure out what you're talking about. Might take me a day or two, but I can start another branch on Gitlab and try out the changes there, as you suggest.
Oh, the _index thing is new since we last talked and I did some Hugo templating.
(Since the I've been writing mostly and didn't have to do Hugo template work, but now for a new site and there are new feautres I dunno about. This is pretty cool, thanks!)
