Here is the list of plugins and tools which I used in FlexBuilder:
- Ant will be accessible as a new Ant window through Window > Other View > Ant and Click OK.
- Flex Formatter plugin (FlexPrettyPrint) . After installation will be added Flex Formatting section in Preferences window.
- TODO and FIXME plugin. If you start comment from TODO or FIXME then window Tasks will contain the whole list of them with references to the code (Window > Other View > General > Tasks) and you will be able to manage this list.
- UML4AS plugin
