Is there a reason the drop-down list for available behaviors auto-populates in the SceneObject behaviors tab, but the field in the Scripts drawer of the Scene Properties does not auto-populate with available JavaScript files to add to the Scene?

Currently, when you begin to type a file name of a JS file in the project, a menu appears just below the field to auto-complete file names. It might not be a fair assumption that since there is already some auto-complete built-in, that it shouldn't be too much more effort for the auto-complete to work automatically for all the available files when the field is clicked on. Maybe it doesn't do this by design?

What are your thoughts?
