Hi,
there is a bug in the current version regarding the autorotation when the view and the fov will be limited on partial panos,
this will be fixed in the next release which should come soon,
about the limitview documenation - you need to press the "show / hide advanced settings" button to show it, but limitview="auto" is already the default value, see here:

best regards,
Klaus
