I have made a really simple (my first) addon that adds an option to the materials specials menu (right arrow in materials tab) to order the slots by their names.
It could be helpful for someone who has many materials applied on one object and wants to keep it the list more organized.
I have not found this feature in any other addon so I decided to make it by myself.
