Xash - Xcode ActionScript Help is new project recently added to osflash.org.

Xash allows you to browse Flash’s help files outside of the help panel. It’s got it’s pros and cons, but I really like it so far. First, it’s a lot faster than the built-in help panel. Second, it allows you to view the help files without having to open Flash, so if you’re working on an AS only project using mtasc, you’ll have quick access to the docs.

On the downside, there’s no searching yet, and you can’t filter the book listing like Flash does, but those features are planned, and since it’s open-source, you could add that if you get impatient. Also, as a downside to Windows users, it’s currently for Macs only.

Either way, this is a great app that Mac Flash developers should check out.
