Hi! I haven’t started using Nyxt as my main browser yet (though it does look nice) but Demeter looks particularly appealing. However, I use a TT-RSS server hosted on my Sandstorm instance as my main RSS reader right now, which is nice because I sometimes like to read through my RSS feeds on the go from my phone as well. Have you considered adding synchronization support with hosted RSS servers like that to Demeter?
It’s been awhile since I’ve looked into TT-RSS… don’t they provide some sort of “master” RSS or Atom feed to follow? Something like your own personal “planet”?
