I made some more progress on the application I plan to bundle as an admin tool with #FedBOX, the generic #ActivityPub server, and #Oni, the no frills single user instance.
It's called #Motely and it looks like this currently.
This usage is meant for connecting to the local storage (disk, database,etc) that is used by the projects above.
However with just minimal changes it can be converted into a full blown fediverse TUI client that can connect to any instance that supports the Client to Server part of the ActivityPub protocol.
