It helps me something good to format my code files (.mxml and .as) with a standard procedure, nice plug-in. It supports both standalone Flex Builder and Flex Builder Eclipse Plug-in. Here is the plug-in update site URL for this Flex Formatter.

Yesterday, i found the Flex Builder for Linux on Adobe Labs. Since i am a Flex Developer i would like to install Adobe Flex Builder Linux(alpha) in my Ubuntu OS. I have noticed here that the Flex Builder Linux is a plugin-only version of the Flex Builder, the desktop version for Linux not yet released. So i need to install Flex Builder as plug-in on the Eclipse IDE.
