By default, Second Life viewers have a sort of "God's eye view" set for the camera. The camera is high above the avatar, sort of looking down. This might be great for avatars set to the maximum allowable height, but for smaller avatars- even just ones with realistic proportions -this positioning is awkward and makes it difficult to move around in any room smaller than a concert hall.
The Z axis value on the CameraOffsetRearView debug setting allows this positioning to be adjusted to bring the camera more in line with the avatar's height, making realistically proportioned rooms easier to navigate, as well as helping people be aware that there is such thing as "up". This default downward angle is part of why I think multi-story malls do so badly on upper floors.
This adjustment could be presented as a simple slider that covered its range of values, added to the Move and View tab in settings.
