For example, Netflix consistently forgets what I have seen and if I don't watch the ending credits it thinks I haven't watched an item and suggests it in the continue watching section. There should be visual indicator on what I have watched, and if there are unwatched episodes in series. Now I have to open it and go to the episode list, which is unreliable. Also, starting video playback is too slow. It's not possible to open items in new tabs. There are no keyboard controls.
