Maybe it is obvious, but you can of course use Drag&Drop to add feed subscriptions to Liferea. You can drag
  • into the subscription list
  • onto the tray icon
and Liferea will create a new subscription. You can also Drag&Drop any web sites URL and Liferea will try to auto-discover the feed URL from it. Note that dragging URLs into the item browser pane or a browser tab will just launch the URL in the internal browser.
