I just noticed on this page that some sorting classes are missing: sorting, sorting_asc_disabled and sorting_desc_disabled which are very useful if one need to override the sorting icons.
Agreed. I'll ensure they are included as part of the updated documentation.
It looks like this is still the case with the update of 1.10. I guess this is a kind of bump =]
Oops yes, this still needs to be done! It won't be immediate due to other ongoing work, but I will try to get it done reasonably soon!
