It would also be nice if there was an offline-capable filter as well, but maybe I missed it?
I also notice the Developer tab is not part of the PWA, which kicks you out of the PWA experience on iOS, even though it seems like that marketing page could be contained within the tab? It might also be nice to link to resources for getting started on developing a high quality PWA, if any resources like that exist.
Now that PWAs on iOS can finally show notifications (if the user wants), I hope more developers will take them seriously. I trust browser isolation more than I trust native app isolation, and a lot of the native apps that I use would work perfectly as a PWA.
