I just discovered the really neat feature of Add to Home screen while visiting this forum on my Firefox mobile browser. It gives me a really nice shortcut directly to this forum, full screen and responsive. It really does almost behave like a native app. 
The main downside is a less than optimal icon:
So I went digging around and it seems that the icon used is specified in a manifest. The manifest for this forum is: https://discussion.fedoraproject.org/manifest.webmanifest
Looking at the icon section of the manifest there are 2 icons listed, both pointing to the same CDN location. I find it ironic that the path has “optimized” in the name, since it is anything but optimized 
. I understand it is referencing a different kind of optimize, but it is still amusing.
It seems probable that these are simply cropped out of the “branding” or main logo that I presume is configured somewhere in the site admin settings. Hopefully Discourse has an option to specify a specific icon for use in this manifest so that we can have something a little nicer on home screens around the world. Presumably the Fedora Infinity logo variant would be nicer in this context.
