The Script Manager offers a way to organize workspaces. It allows you to
define "folders" in which you can store your scripts/workspaces. The folder
menu provides options to import and export whole collections of scripts to
a file. The script menu offers options to "tear off" a script into a workspace,
"bring in" workspaces, and to dump and load individual scripts to files. Works fine in every Squeak version I've used since 2.8. No known bugs.
