There are many ways in which you can try out your ideas in Squeak.

1. You could put together a story board in Squeak with a few EToys and some 
simple scripts. See attached picture for an example.
2. Use a Holder (turn on show thumbnails mode in playfield options) and put 
all your story boards (playfields) into this. Drag each story board out to 
edit it.
3. Use the Book EToy and use one page per story board. Then you can sort the 
pages using page sorter.
4. Create one project per story board and use the 
Catalog->Multimedia->ThreadNavigator to create a story line out of these 
projects. The "edit thread" option displays thumbnails of all projects.

Enjoy .. Subbu
