I didn't realize that Newsboat has Miniflux support! That means you can read your feeds from the console and keep everything in sync with the web interface or any other client software. I will try this out later.
Recently I set up a miniflux instance with the intention of using it as a backend for newsboat. I'd been using newsboat on its own for a while and I liked it, but wanted my feeds accessible on other devices. Turns out I liked miniflux's UI so much that I didn't even bother finishing setting up newsboat to be its frontend. Now I'm 100% miniflux, using the web app on both desktop and mobile.
