Example from documentation
GALLERY
tooltip:title,descripton crop:1,1 sort:desc sort:asc hide text-center hr(horizontal rule) title-xsmall title-small title-large title-xlarge frame hover title-clamp:1 description-clamp-3 landscape portrait]
I could not find any other examples of SORT and other instances of options available for use within the gallery or menus etc...
It only talks about the numeric prefix and the Gallery example above.
We really need to have EVERY variable/option available for use on each page and the available options / settings for it. But the documentation is a Work-In-Progress.
But Karl probably won't have time to dedicate to *everything* being included in the documentation until X3 goes live and publicly available.
