Before Gideros I used Flash to make games. Say what you will about Flash as an SDK, but the built-in timeline animation editor is one of its strengths, especially for creating menus and UI.
Could Gideros support the Flash animation format (it can be exported to XML), or is there a similar tool out there that can handle nested sprites on a timeline?
