Hello. The only settings exposed are the HTTPS toggle on the general options screen. Otherwise, the plugin re-uses core settings.
It uses your site icon as the icon in the web app manifest, and it uses your site title as the name
. I am getting the install prompt in the URL bar when visiting your site.
The PWA plugin is primarily a set of APIs which are being iterated on to propose for integration into WordPress core. Themes and plugins can then integrate with the APIs to tailor the PWA experience for a given site. We’re still looking at what makes sense to include in a default set of functionality, but one such extension plugin you should check out is this “Basic Site Caching” extension plugin I made for the PWA plugin: https://gist.github.com/westonruter/1a63d052beb579842461f6ad837715fb
It enables a network-first caching strategy for your site and ensures that the assets and uploaded files will be available offline as well.
