Thank you.
Please restore the ability to sort alphabetically, or else make it possible for users to control how they want their pinned items sorted.
I have a pinned variety of useful files, some many years old, and cannot always remember the order in which they were created or modified. Alphabetical sorting is much more useful to me.
