That's one of those little annoyances that have been with us since the upgrade.
About half the boards have hard to read colors in the quick navigation box.
I also liked the way it used to work better.
It used to center on the board you're on.
You could start on Platypus Comics, then by default the Cafe would be in range, then from there the Comic Book or Entertainment board was in range. I could navigate up like that.
Instead the quick navigation is always set to the top and I have to use the scroll bar to get to the board I want.
It's a stupid small thing, and I don't know if it works different for others, but it changed the way I navigate the boards.
On the plus side, I'm glad to see the return of "The threads below have not been updated since your last visit." when you hit new posts.
Especially since I use a font that's two sizes larger then default and the new formatting makes it so I can't see the time of the last post.
