Maybe make the unread posts notification red instead of yellow, like it used to be? Red's easier to see.
Also, probably just 'cause my screen res isn't very big (1366x768) but it's all kind of big, y'know? I can only really see one post at a time without scrolling. Not a big deal but hey you did ask for feedback!
I mean I bought a TV 4 months ago, 32 inches and 1080p, it looks so nice I don't see the need fr 4K right now. Especially 'cause I don't actually watch any TV, I just use it for PS4, and PS4 games don't display in 4K anyway. My phone is the Nexus 4 which I believe is 720p.
I remember just a few years ago everyone said anything above 720p useless fot 32 inches or smaller screens. Now you can't have a dinky 5 inch screen that isn't at least 1080p or people complain.
