(For your "DuplicateMovieClip AttachMovie" section)
I used the code you had and it didn't work,
I mixed and matched in many different ways, it didn't work.
CONS:
Your Code doesn't work and you did explain ok, but not well enough for beginners to understand.
PROS:
But you made it look pretty and the use of the side button/panel is quite nifty. And your color themes are interesting.
