Its not the panels I want to scroll. Kind of the opposite. The list of songs (and rackspaces) on the left side. That’s what I referred to as difficult to grab that scroll bar even with a mouse, much less with a finger touch. It is a VERY skinny scroll bar. Both the left and right sides of the panels have huge real estate for grabbing and scrolling the panels themselves, but we don’t need both sides really. Or not as big. That way making more space for a wider/larger scroll bar for the songs/rackspaces scrolling.
Or, as an alternative, it would be nice if a similar system actions existed for scrolling songs/rackspaces.
