Threads "Quick Navigation" could stand for some improvements.
 

Overall* I like the new way that "Quick Navigation" has been designed. It's much cleaner and still provides quick access* but one thing that it doesn't do is provide a quick way back to forum you're currently browsing.

In other words* when you click on the drop-down* the default area (in the center) should either be the forum you're currently within* or the very top should have a "Go to Currently Viewed Forum" or something. Because the way it is now* you have to scroll through the long drop-down just to go back to the forum you're already in.
