A large part of my work is writing about and sharing the Vuo story. We believe there are all kinds of people who will embrace Vuo once they discover it’s out there. So, my efforts include helping create the Vuo website, writing press releases, submitting conference proposals and generally figuring out how to create excitement and how to spread the word about Vuo. I occasionally help out with Vuo e-mail support and I'm part of the think-tank called "Team Vuo."
Yes, "a less restrictive shell command node would allow much more custom / powerful things ...", but that may not be good in all cases. For example, an unrestricted shell command node could delete all files in the user's home folder, or remove, copy, or scramble user data. It would also be more user-friendly to have a node specific to iTunes than for people to have to use the shell node with osascript.
Using Vuo's Make Button node, which fires an event when it is clicked, could create a result closer to the scrollable/clickable interface you are seeking. You would have to change several nodes in Bodysoulspirit's demonstration composition to implement a column of buttons. Instead of creating a list of text layers, you would need to create a list of texts that would become action button labels. I've attached a Vuo 2.0 beta composition that demonstrates that. As to scrolling text, there is a Vuo composition in the node gallery, Scrolling text with motion blur, that you might find helpful.
