in eg. Rhino its possible to assign middle mouse key to a command which I set to _ZS which means zoom selected, so the selected object becomes center point of the space mouse.

Not sure if you consider it related, but I want a "reset view" to set the view back to sane defaults. When I'm using SpaceMouse (and sometimes mouse) I can "lose" the objects and orientation -- I want a "view 0,0,0" button. (not just for spaceball/trackball, ideally in from any time from ui)UI

Please make this an option that can be toggled (like Blender). I'm still waiting (ever patiently) on LightWave modeller to receive plasticity and Blender's default orbit/turntable rotations.

This is very useful feature. Used it in Modo and now in Blender. But, dear developers, if you're going to add it, please implement it as a switcher. This way we can quickly choose the right mode

I am of the same opinion.

I get stuck at the max rotation all the time, this would be great.

I'm surprised this hasn't been implemented.

This way of rotation is necessary for complex modeling.
