I'm planning to drag other projects in the Etoys folder on the custom USB drive into the new default project to generate thumbnails making that screen function as a simple launcher for a collection of projects.
The real world user scenario will be my youths in Zambia doing this change on a copy of the Etoys-to-Go image on a USB drive to prepare some projects for staff at partners like the Ministry of Education to view on their locked-down machines. Etoys-to-Go is shaping up to be a great solution for this situation.
