I recently noticed that the alphabetic sorting is in computer standard-upper case before lower caseand not in user application standard-case insensitive. Most office applications, e.g. Excel, do not distinguish case for sorting.
I don't know how much trouble it would be to change the sort method. If not too hard, I think it would be useful. I think users would appreciate it, or at least find items beginning with lower case characters where they expect them.
Thanks for your consideration.
