-drawing modes. (Shaded, wireframe, non-lighted)
-Angle rotation snapping to grid (for things like 90 degrees, 45,180, maybe a toggle, right now it seems to snap to all angles which makes it really hard to rotate exactly 90 degrees)
-shade the horizon plane so I can see where an object is touching it (if I'm moving an object up and down on z axis)
-main grid line should have a little more thickness so I can easily tell where 0,0,0 is
-symmetry drawing tool so I can make symmetric objects
-I think by default if your drawing a shape using lines it should default to a line when you get to the next point. If I'm using curves the next point is a curve as well.
_I'm finding that I need to edit the 2d shapers after I no longer can sometimes. It would be nice to be able to toggle editing the 2d shapes.
Overall I really like it. The pencil manipulating objects and fingers manipulating the tools and camera are great. really looking forward to start creating some 3D printed things. I'm very eager to go from iPAd to cura to my printer.
