What 'scrolly arrow' is that, GoM? The one down the side? DS has that, plus mouse-wheel scroll. You can also hit Home or End to go to top/bottom of a library folder. You've got back/forward/up buttons at the top, and you can use small icons for less scrolling, if your libraries have tons of stuff in them. Not sure what else they could add, to tell the truth.

Re the list structure - As default? Well, not for me, thanks. I always set mine to tree. But everyone's different.
