At the moment, if you have your magazines named according to date (2019.01, 2019.02, etc), the latest versions are shown at the bottom of the category when sorted alphabetically. This would be fine, but the icon for the category then uses the oldest version!
By reversing the sort order, the latest version would be at the top, with the latest version shown on the icon. This could be implemented by pressing the SAME sort button again, for example:
Press sort alphabetically, sorts a-z
Press sort alphabetically again, sorts z-a
Cheers!
