I really like this app. My only suggestion would be to add a "Refresh" button or option in the menu. I minimized the app and went back to it about 20 minutes later and it was bringing me to the wrong article comments and then it gave me a 'network error' (guessing the page expired) when scrolling. Closed the app via recent apps vs minimizing it and restarted it, worked fine.
Aside from that, I truly like it.
