This is a feature I was looking for myself and due to the amazing work of @pfefferle on the #ActivityPub plugin things like this are now possible to realize pretty straight forward. The hardest part for me is getting UI right.

This was a little side project, and I was challenging myself how fast I could get a prototype to work. But #Gutenberg and #React is something you do not get used to in an hour. I'll try to release the source soon.
