I like that this project seems so open, and inclusive for loads of skills. And it might be hard to describe what is needed, not even sure if all is settled, or if there are wishes for new ideas too. The thing is, if it was listed one could find interesting things to learn, like I would love to learn blender. And to learn it with some actual goals is easier I think than to just play around with it. Like I did for the Ryztools app. I had almost no clue about phone development, but I had the motivation to learn it, and I think it turned out well.
