Okay, I seem to have been able to find an answer on my own - I found this post: http://forum.powerampapp.com/index.php?/topic/2832-shuffle-info/, which explains to go to the folders/library list, select your playlist, long click your playlist, and select shuffle. Doing that started the playlist and showed the shuffle icon with the three bars to the left of the crossed arrows. So, I guess I'd like to turn this post into a feature request: A MANUAL!! Or, at least a better contextual explanation of what each shuffle mode does. They don't really make sense to me (obviously, since I saw that option and didn't realize it did what I was looking for). In the short time I've been in these forums looking for an answer to this issue, I've seen other remarks that a) people don't understand what a lot of the features do, and people (including me) would like a detailed manual. The app does a LOT, and a detailed user manual would greatly benefit its users!
