As one of Vuo's developers, I work on Vuo's engine (the thing that makes compositions run), work on nodes, and write documentation. You'll see me on the forums answering people's questions about Vuo.
I've been developing apps and frameworks for several years (since I was in college). Pre-Vuo projects include Kineme Quartz Composer plugins, iOS apps for education, an app that analyzes photographs of tomato slices, and software to help people with disabilities use talking keyboards.
I enjoy using Vuo to make live music visuals. My hope for Vuo is that it will grow into a community of people of diverse backgrounds and identities making lots of different artistic, useful, unique, goofy, beautiful, crafty, wonderful compositions.
So you mean all other .plist OSX files would work as well ?
Good question — I meant that Make Tree from XML would handle property lists stored as XML text, like the iTunes file. But usually macOS stores property lists in a binary format (if you try to open the file in a text editor, it's just a bunch of weird characters), so that would be a separate node, beyond the scope of this feature request.
Thanks for pointing out the existing feature request for reading iTunes playlists.
