Using version 68.5.0 (32-bit) - Addon works!

Had a very hard time finding how to use it.

" HOW TO USE:
Use the "Tools" button on the menu bar along the top,
NOT the Tools button under the hamburger "Options" menu.
Make sure you have the menu bar enabled
by clicking the hamburger "Options" button at top right,
then "Options" and you'll see the Menu Bar option.
Make sure it has a check mark next to it, verifying that it's enabled."

In Tools menu, click on Manually Sort Folders...
