@rizzi Congratulations. Love so many of the ideas here.
Saw your list of future todo items, please add a vote for display customization. Reeder Classic became my go-to app initially due to the ability to use giant fonts across all the UI. Need this to be able to move to the new app, exclusively. Also don't need the article text or thumbnail images in the list view, but that's a lower priority.
Again, great work, and looking forward to using the app even more!
