@pfefferle Some great suggestions already.
For me, the ability to fine tune how the Fediverse profile is presented would be great. I believe there’s some work on the roadmap to better define how the Header Image, Icon, Biography and other profile details are populated. It would be good as well to be able to add validated links to the profile at the blog level.
There may be a capacity to do this in the separate webfinger and nodeinfo plugins, but those are too opaque for a non-technical admin.
