Okay, I will try to describe it:

First in Dr. Geo there is user scripting. The idea is to let the user define a computing object he can plug on a sketch. This object receive an arbitrary number of objects as arguments selected from the sketch by mouse. This script object is a class, subclass of DrGeoUserScript, and each use in a geometric canvas create an instance. This video exposes this:

• Two vertical panes:

1. at the left, the script classes, but it is the script name (as given by the user) displayed
2. at the right, the methods of the selected script
   

• A large horizontal pane with the source of selected pane.

The attached screenshot shows the wished user interface as writen with Glamour.

However, I am not sure what the current problem is. Could you describe it again in more details?
