Danno has been busy revamping the UI, taking into consideration some of the remarks and ideas Romain expressed a couple of months ago. It is not a Filthy Rich GroovyConsole (yet) but its sexier and sports more functionality than before. The same richness should be available in GraphicsPad and that is what you are going to get once it is released.
A curious thing happened once I finished adding the new actions, I demoed the new app to Ixchel (my wife, she is also into Groovy

On a related note to the Filthy Rich Book, I haven't finished chapter 2 but it has already helped me detect and eliminate thread bottlenecks on the GraphicsBuilderDemo and GraphicsPad applications, so far so good

Keep on Groovying!
