AS3 Library Recommendations

[russianreversal]

So I've been picking up Flash recently, and I've just in the past week jumped into using external libraries like Graffiti. I was wondering if anyone could direct me towards any solid, simple (or not, I pick things up quickly) libraries that they've found useful. I'm not looking for anything specific, as I'm trying to get a general feel for what I like in Flash, but networking is not one of my stronger points, so if you could keep that simple somehow that'd be great.

This is more of a hobby than anything else, so I don't NEED these, I just want to save myself some time.

Also, as you can see from the title, I've only learned AS3, so AS2 libraries aren't going to be of much use to me. That said, you can still post them for anyone else who needs them in the future.
