Patch release.
the orbit still weird, on blender it is different, lets say I have a cube on middle. on C3 and blender if I press middle button and drag to down it orbit the camera around the cube and I can see the top of cube, nice, it makes sense. On blender if I press middle button and drag do right, camera orbit the cube and I can see the side of cube, nice, but on C3 if I drag do right side, it tilt the horizon line which is weird, no much useful to tilt horizon line, usually the ground still and I can orbit the object. and need orbit on selection, like if I click in a obj the focus of orbit must be the center of that obj, right now If I have a obj far from each other I need keep moving to camera to side to try to focus the pivot point of orbit,now it is orbiting around the layout not any specific obj, I hope it makes sense.
