So once this is at a point where you consider this something to expose a broader audience to, I have a request:

There is no decent (read: functional, not even Fedilab is working anymore) native client for pleroma or newer Mastodon for Sailfish. There used to be one (Tooter), but it's development wrt the Mastodon API is stuck. Since the framework of choice in Sailfish is Qt, it should be doable to build this with some reading for Sailfish (or even get into the Store for this platform or alternatively the "Harbour" (community repo)).

I might get around and try and build this myself for sailfish just to see if any changes are necessary.
