The possibility to run scripts directly from Blenders Text editor is awesome. In most cases the text editor is enough to create an addon. But for larger Projects you need a real development environment. There are several hacks and workarounds on how to achieve a semi integration of environments like Eclipse in Blender. But now you don't have to care about that. The simple development tool addon is a realtime integration of eclipse (better py-dev) projects into Blender. This addon comes with a few handy features. For example an automated version management and an automated backup program for your sourcecode. So don't waste time on setting up your environment.
