Add a filter to the rune trader so you only have to see the runes available for your primary. Make it sticky so if you're trying to catch a rune that is hard to get you don't have to reset it each time. This would eliminate the scrolling and trying to find a rune you are after.
Also, the fonts in the rune trader display always overlap each other. not sure if it's just me or a global issue but it has been this way through a couple of video cards.
