Not really a feature but on CS3, go help>about and then click on the second (C) sign (just after 'Flash'), and a bunch of pictures of the developers appear :D
+ when you're running the swf, press Cntrl+B (or view>bandwidth profiler), it brings up a nice graph, which shows how big filesize-wise each frame is.
Webcomic?
Recently I've been considering creating a webcomicy website, so to start myself off I've scanned in a couple of pages from my sketchbook. If you guys could give some feedback I'd be really happy.
Bear in mind all of these are just raw scans from paper, no photoshop touch ups, so they would look nicer if I was going to do it more seriously and make final drawings from them, at the moment they look very biro-y.
