The ability to import a Flash Professional .fla file format into Catalyst would be a great benefit. Especially since there was an official workflow between Flash Pro and Flex 3 for creating graphical, stateful skins for flex (ie File...New...Flex Skins). It seems strange that in the new workflow, Flash is not treated as a first class citizen such as Illustrator or Photoshop. For large libraries of Flash built skins, the process of converting these to Flex 4 skins is quite painful as the current builds of Catalyst merely provide Importing of FXG. When a Flash-created Flex skin symbol is exported as .fxg from Flash, and imported into Catalyst, only the first frame/state is available.
