It’s all about the UX I think.
Camera’s Rotation/translation acceleration & de-acceleration puzzle control would be fantastic in order to create better UX in my projects.
At this stage it would be very helpful to me if I could control the mouse/touchpad scroll smoothness (and hopefully re-bounce) to the camera or anything else.
Also, translation limits on the camera would be ideal, so users cannot navigate out of the “world”…but that’s another thing maybe.
