Beta 12 is now available. Sorry, no major changes as I said earlier.
But now you can export a portion of the time line to an ILDA file. For example, you can use the mutiple layers to combine various frames and effects. Then you set the start time and end time by right clicking on the "time" portion of the timeline and setting the green and red markers at the beginning and end of the portion of the timeline you want to export. Then go to the File menu and "Export ILDA". If you are creative you can do some really cool stuff that you can't do (or do as easily) in a single frame editor. For example, you can take a frame of a square and a frame of a circle and combine them in different layers. Then you can play different effects to the square and circle frames. You could end up with a new ILDA file of a square orbitting the circle or whatever.
