Change radii & speed of "rotate view"? When I hold MMB, I rotate my view around a point.  Somehow, I accidentally caused the camera to rotate around a large circle.  Then, I bound the camera to a marker, and the view jumped to the origin, and the effect was removed.

How can I increase the radius of the point around which the view rotates via MMB?  How can I increase the speed of view-translations (move/rotate/dolly)?

Click numpad dot/del to focus camera transform around selceted object origin, then zoom in /out and it'll be cool. :)
