@gandalf3 Hi! :) Well, I was wondering about that type of layout editor in general, not just in blender. Like, Adobe Illustrator allows you to group things and them move them and still maintain connections between vertices that aren't being moved.

So, I was wondering if there is a name for that style of UI
