better camera controls/button to reset camera to default position

[HEYimHeroic]

hi there. this program is working wonderfully so far, but the camera is just really hard to use. i'd prefer a different type of camera, preferably one where orbiting the camera with the left mouse button doesn't also rotate the camera a bunch. at the very least, a button to reset the camera to the default position would be a good fix as well, since it can be hard to rotate it back even again. thanks
