Patch release.
About the 3D view editor, I know free look method and it is kinda painful, one thing very useful to avoid user get lost is a option called "orbit around selection" from blender, so we dont need to keep moving around and so on, we just need click in one obj and the orbit camera will be around that obj, scroll to zoom maybe ?
You can click and drag the middle mouse button to orbit.
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.
