FEATURE REQUEST: Snap to 0 in Viewing Parameters

[AntiochInteractive]

Almost without exception, I set my 360s to a 0 Degree Tilt. When using the Viewing Parameters editor, I'll often reposition the horizontal pan setting and involuntarily change my vertical.

The need to reset this to 0 adds an additional, unneeded step -- and while it seems trivial, when you're processing 30 tours in a day, it would be great and keep workflow moving if the vertical could either be disabled, or if Pano2VR would allow snapping to zero.

What do you guys think?
