Easel may have (at this writing, anyway) one of the world's lamest edit menus. It has two entries, Undo, and Redo, and to be perfectly candid, it can only undo and redo a fraction of the stuff that Easel can do. This will be revisited, but because it's a convenience (you can always undo and redo stuff yourself, with just a bit more effort), it might still be pretty lame in the first release. We'll see. I suppose I could just remove it. Maybe I will.
Late breaking news: the Edit menu gets slightly more useful when you have used auto arrange to generate multiple arrangements.
