Just upgraded to V20 and I really am liking the Component Values editor. This really does take a lot of pain out of sorting my libraries. It is a really nice improvement.
What I want to do now is be able to create a component where the component reference is on my silkscreen layer but have the component value on a different layer. This enables me to create build sheets quickly with component values already displayed. I just have to tidy the positions up. This really does help when I am building 5 prototypes up as the values are all on the one sheet for me.
