Something atypical about my setup is that I wired up miniflux webhooks to n8n and gotify so that when I click "save" on an entry, I get a notification for it. It's a rudimentary way to setup a "read it later" list.
I love miniflux. Switched from inoreader when they started imposing more and more limits and changing the UI.
With miniflux I have not limits with unread items/feeds. I can set check frequency to what I want and I actually don't need the app as the www ui is just brillinat!
