Script Port offers user-friendly solutions for your script running needs in Blender. With this handy addon, you can easily access all of your .py scripts right from the 3D viewport panel, without the hassle of copying and pasting into Blender's text editor.

Besides being able to choose a custom directory to load scripts from, with Script Port, you can also open any selected .py script in your default system's editor, making it even easier to make changes and edits on the fly.
