Let me do the job for you (counter 952+ 1)
(irony off).
By simply reading one of the addons description I found that they just do what the game settings allow you to do too:
Code:
camera preferred parameters: distance, field of view, and horizontal/vertical position. It overrides the regular camera settings.
It just moves the camera on the x/y axis and it does not turn the view from you to NPC or vice versa (which is something that addons cannot do afaik, but you had asked for if I understood your request correctly).
I guess the other addon does the same then: Change game settings (which you can manually change by pressing ESC key -> settings -> Camera ...) based on profiles or other triggers.
