Something that could be really useful would be the way for someone to distribute a “compilation” of apps that would basically show in the launcher as a non-customisable folder - similar to the ‘switcher’ used for pulp games, but otherwise simpler
The pdx itself would contain the icon and just additional pdx’s in their own sub folders. You could also potentially have an “autoexec” pdx that runs the first time (or every time) the folder is opened, before quitting back to the regular folder view.
This would allow people to distribute “demo disks”, zines, compilations of small games, budget re-releases, etc
