Hey, just downloaded your mod. I love it. Just a thought, if you have access to Unity's Screen.showCursor property, you could hide the mouse while the user is adjusting the wings. That would prevent the problem where the mouse moves off the wing during editing and you have to keep dragging the mouse back over and over again. It's a really simple API too, just Screen.showCursor = false; when starting the edit, then back to true when you're done. Here's the docs page for it: http://docs.unity3d.com/ScriptReference/Screen-showCursor.html
