Problem: Sorting a select field puts blanks at the top. Often, we want blanks to sort at bottom.
Suggested Solution: Sort the select field in descending order in the view. That puts blanks at bottom. However, then your select values are in reverse order. If you could sort the select field options (in the field) in descending order then all would be good in the world: blanks would be at the bottom and options would be at the top sorted in ascending order.
Implementation: Best part, implementation is super easy. Currently you can only sort options in a select field in ascending order. Just enable clicking on the sort icon to toggle between ascending and descending sort of options in select/multi-select fields.
