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 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.
Estoy practicando para ser competente en español. Si publicas en el foro en español, trataré de responder en la misma manera.
Oops, yeah, that documentation is wrong. Thanks for catching that, unicode.
Could you describe how you intend to use the U/V expressions? Like, what is the task you're trying to accomplish, and how would the ability to manipulate UV texture coordinates independently make it possible / easier than just using X/Y/Z expressions? I ask because a concrete example helps when thinking about possible improvements to nodes.
I don't have a very good answer for your question about timeframe for fixing the graphics-related crashes, sorry. For the past several months, we've been working on features/fixes that were originally planned for Vuo 1.3 and releasing the smaller or more self-contained ones in the 1.2.x versions. Since the graphics changes are complicated, they're still planned for Vuo 1.3. I expect that will be some months away.
