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.
We're continuing to make progress on working around this GPU driver bug. We had suspected that certain changes to the graphics system (eliminating the use of OpenGL shared contexts) would fix the crashes/hangs, and we confirmed that they do.
We've started using computers with AMD GPUs more frequently, and have also observed similar system-wide hangs when using Final Cut Pro X on those computers (without any Vuo compositions running). And other people have reported issues using Photoshop's GPU acceleration with AMD GPUs. So this seems to be a fairly widespread AMD driver issue :^/
Another piece — "select a bunch of pre-connected nodes, right-click them into a macro and all publishing and cable connections are done for you" — doesn't have a public feature request, but we're already working on it and are planning to release it in Vuo 1.3.
