DOK

Dok is an AIR application (consistent experience through all operating systems) that provides a UI for Adobe's ActionScript 3 and Flex reference.

Its main purpose is to offer access to all classes properties in a simple and slick user interface.
At first Dok was a proof-of-concept application for HTMLFixer (a class that converts HTML page source code into valid XML) but it became so useful it would have been a shame not to share!
