I had a thought for Anime Studio while watching some Flash tutorials. Now it may be a longshot but I figured I'd post it on here anyway just in case someone sees it and thinks it may be doable! (Yes I know I am posting it in the Feature Request because I feel it would be too much for a .LUA script).
Right so my idea is this. The current "Layers" available in ASP that we already have are ("Vector", "Image", "Group", Etc.) would instead be called Assets and that becomes our library of content. Then, something similar to the Sequence Editor and the Timeline combined become a more universal "Layers" such as in Flash, ToonBoom and After Effects.
My reasoning for this would be to create a central "MovieClip" so to speak. Not to differ from ASP'S already awesome give each ("Vector", "Image", "Group", Etc.) it's own timeline, because I love that! But a place where you can edit your movie all together by dragging assets INTO layers, and then placing the sequence of the layers!
Maybe this is kind of what Layer Comps already do? I'm not sure because I haven't messed with them at all - but just a thought - would love to hear anyone else's ideas or opinions

Thanks!
