The FlashDevelop Team and the Haxe Foundation have joined forces to release a Haxe-specific version of FlashDevelop: HaxeDevelop. HaxeDevelop offers first class support for Haxe development: great and fast code completion & code generation, refactoring, projects compilation, debugging, plenty of project templates, etc.
HaxeDevelop can be downloaded here:
http://haxedevelop.org/ (free + open source)
I’ve created the logo and the website for the HaxeFoundation.
