hwadock, that is mesmerizing!
puzzler, no not yet. Sorry, there are a lot of things going on and since your Spine is working, it's lower priority. I do realize it's annoying though and we'll get to it. 🙂
Erikari, wow that is a strange problem! Can you email a project that shows any of the problems you are experiencing? contact@esotericsoftware.com We need to be able to reproduce the problems so we can fix them, so anything you can do to help with that would be great.
BinaryCats, you could rotate bones before v3, but v3's nonuniform scale allows you to squish child bones along the parent bone axis. This means when the child bone it rotated, it's tip will trace an ellipse rather than a circle. When you attach images, they are squished in the same way. This enables things like hwadock's cool effect (the fireballs are moving in an elliptical path) or squishing a rotating image to give it perspective.
