It would be very nice to be able to have transparency for the backing color of the Vuo Editor. What I intend to describe is similar to the effect of using Kinemecore with Quartz Composer’s Editor, and choosing an alpha value of less than 1 for the Editor “background color”.
I also think a selectable grid with similar color control would be nice… though maybe not the same priority level as background color transparency, which I am finding to be a bit of a problem.
