We've heard from some Studios that they'd like more options for sorting groups, including being able to save the advanced group sort to a page.
For example, build a page of versions where all listed versions are grouped by "Link > Shot", then the ability to sort the resultant groups be the "Link > Shot > Latest Version > Date Created" field.
If this is functionality you'd like to see in Shotgun, please add your +1 vote, and use case.
