Thanks for updating the admin views to allow for user-defined sorting. What would be a very helpful modification would be to offer the admin the ability to save a selected alternate sort criteria to be the new default.

In the alternative, perhaps you can retain a selected alternate sort order for the duration of an admin's session?

At the moment, if I change to a different sort order, open a page, then dismiss it. I return to the OEM default, versus the sort option I selected.
