Hy.
The camera target only alows to change where the center of the camera viewport is looking.7
Maybe you could add an option to change the offset of the target relative to the camera.
I mean i would like to target the head of a character but i don't want it to be in the middle off the screen.
Translated in CSS in would be like top: 10%; So that when i zoom out the character would bee full screen. and when i zoom in the head stays on the screen.

Hope i you understand what i mean !
