The one thing I couldn't get past when looking into Unpoly is that if you're in a deeply nested modal/layer, and then refresh the page, it just shows you the most recent modal as a full page. My expectation is that when you refresh, instead it would keep you on the base page, and then wipe all the modals.

Unpoly by default changes the browser's history to the url of the modal. Thus when your refresh you'll get exactly that. You can modify that behavior with up-history, see here https://unpoly.com/history-in-overlays

You can set up-history="false" and there'd be no navigation when opening the modal, so when you refresh the page it'd refresh the parent layer not the modal.

What's more arguable I think is how pressing the browser Back button doesn't preserve the layers, but opens the previous page as a full page. I think that can be changed in a config somewhere, though.
