That's exactly it. Forums with that function readily available on the top level (not a pull-down menu) are much faster to go through. I read a number of forums every day and it makes a big difference in speed and convenience. Even more with FireFox, because when FF has been up some days it's acquired hundreds of megs or RAM, and it takes 10 seconds or more for me to open that pull-down menu when it's at the same time loading all the new-post pages which I'm loading in different tabs.
