"Look parallel to floor" keyboard shortcut in Inside View
The keyboard shortcuts are good, but I miss a very useful one:
in Inside View: "Look parallel to floor".
For example, it could be Spacebar, or whatever. When pressed, it should bring the (virtual) viewer's sight parallel to floor (or anyway, whatever is the default "comfortable" position that is used by default).
In other words, pressing it would quickly "reposition" the head in its rotation around the horizontal axis, to have no rotation from the default starting value.
