Script Watcher

Script Watcher is a blender addon I developed to assist in developing other addons. What does it do? It allows for a script to be developed outside of blender in an external python text editor. How does it do this? It watches the external script for changes and when a change occurs, it reloads it inside of blender.

It also has a few other useful features:

• Print script output to blenders builtin python console, this is convenient because you don't need to worry about keeping a system console open, you'll be able to see the output right inside of blender!
• Console debugging mode. While in debugging mode you have access to all the scripts global variables. This can be enabled on each console.
