- who is the target audience for this dialog?
I think it is both.
Developers for obvious reasons, but as a user I prefer to set my own view position different from what a developer may thinks it should be. Not to mention In reality you have different height people. I think there should be an easy to use interface for user to adjust this position if they choose to do so. I really liked the idea of the GUI interface (if it worked correctly), but I was never able to get it to tune in small enough increments to be of any use. However, a value input field would be nice to have for other reason, but mostly from a development perspective.
