Your "PortableApps.com Platform Features" page for 10.1.2 says 'You can organize apps into folders automatically or create your own that work the way you think.'
I am running 10.1.2 (according to the platform help/about). I cannot find any evidence whatsoever that this is possible nor any documentation whatsoever about this feature except the claim on your 'features' page and a few queries about it from several years ago on the forums.
Am I missing something obvious? How do you do this?
