I do like the pause/play button for the carousel...but the carousel is unresponsive atm, just sits on the first slide.
I really, REALLY like the up/down arrow button that shows up on the right side of the screen that keeps me from having to scroll all the way up/down a thread to get to the top/bottom. I think it would be better if it was possible to make it "always visible" and did not require a tiny scroll up or down to make it appear. I realize you have to balance screen clutter with available features though. Can you make it appear when you hover over the right scroll bar?
