After adding an index.html if I want updates of that file to show automatically where do I add it?

It looks like watch-dirs is only for source.

And there is watch-css but no watch-html

Yeah, I think you gotta refresh the page for that. People rarely touch the html directly in CLJS

Well, I guess that's most js dev these days

I also assume it's hard to reliably swap out changes to index.html without completely reloading, so you won't be able retain app state

In SPAs, though, most of the DOM lives in JS/CLJS anyway, right?

Okay, I'll just reload manually. Not that hard. x)
