It would be great to have the ability to click a symbol on stage and swap it with another in the resources. They had this functionality in flash and it made delegating tasks much more efficient.
It would also be great to have the ability to double click a symbol in the resource folder and edit it independently of the scene. I have found as I build more and more complex sites, that if I have several instances of a symbol on a stage, if I go in to edit, things slow down to a crawl as it is trying to render everything.
Thirdly, the ability to organize a resource directory by folders would be incredibly useful.
A few other aside questions:
Why is every element on stage further wrapped in a containing
Would it be possible to make it compile the external .js files within the main, so that there were less calls to the server?
