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."
At some point we may need to remove the deprecated nodes, but we haven't set a timeline for removing them. It mostly depends on how much effort it takes to keep the deprecated nodes working (which so far hasn't been much).
As for multiple "Set Window Properties", you can chain nodes, as seen in the "Show Primary and Secondary Window" example composition under the Window examples.
