When working on an animated object that is moving quickly, it is very frustrating to have to keep updating the viewport position to track the object.
I end up having to create cameras linked to the object so that I can monitor what is happening to it. For instance imagine a character rig in a car... and i need to animate the fingers...
I have to create a camera and link it to the car and always use that camera to adjust it.
It's not that difficult -- but it would be much easier if the viewport could lock onto the object. Whether it be perspective view or top view, the viewport could have a toggle where it keeps the object in the same relative position within the frame.
Would be very useful.
