Folder Element/en
Introduction
Folder elements are used to group related items. Notice that any action block item can have subitems. Besides being used to specify user-defined action menus (see Project Description Editor) , folders have no special semantic relevance.
Useful Trick
Add a folder named "Playground" or "Examples" or similar and place compound action blocks which demonstrate key features or low level access functionality. Other users may later easily find those and play with the examples.
