There's always a phase of developing a shot where I am moving the camera target and adjusting the camera parameters - I have to keep switching back and forth between the two and selecting and deselecting.
It's especially annoying because this is the phase where I like to lean back from my desk, put my feet up, and take time to consider how shots look.
I see no reason why the camera parameters cannot be edited while the target object is selected.
Being able to edit the camera parameters while the camera's target is selected would make life easier.
