Thanks Adam, I can now see that I have this option if the whole interface is a list, but not if a list is added to a dashboard interface, which is what I'm working with. Thanks for the answer!
It would be great if this could be added as a standard interface feature (allow user sort, filter, and search buttons for grids, lists, etc. elements in Dashboard or Blank interface layouts) for greater usability and customizability across different users! This is a really helpful feature that seems to only be available on List interface layouts.
