Ive decided to share a Flash Command im in the process of developing to make you all think about the possiblities of JSFL. This particular command is fairly basic, and its purpose is to enable developers to organise their flash movie. Download the code here and copy the .jsfl file into your Commands directory and then run it, by starting Flash MX 2004 and then selecting the Organise Library Command from the Command menu. Im presently implementing a user interface using XML 2 UI which will allow users to customise the organisation settings. I plan to implement organisation of layers into relevant folders and automatic symbol renaming. Note: I know that this command needs improvement, its just a teaser! Im also in the planning stages of an extension which will import/export UML documents from/to flash classes 
Expect more on JSFL & XML 2 UI shortly!
