Mark, I think I saw your post and thought it quite a workaround. Accessories must be included. Of course, I think VWX defines things that aren't actually accessories as accessories. The 2D components need Loci. I need to be able to yoke back, out, or up. The 2D body needs to move with focus.
I think VWX has long thought SVs are 'done,' while the users have never been satisfied.
With all due respect to your ability to make them work. I always ask how can I explain this 'feature' to a new user. If I imagine the new user's eye rolling backwards in their head, there is a problem. With SVs, I see eyes rolling, no spinning, like in a bugs bunny cartoon.
