The "Viewer"
The "Viewer" is a dynamic graphical Inspector and Browser. To get a Viewer for an object, drag from the cyan handle of its halo, and a Viewer will stick to the mouse; place it wherever you wish.
You can use the viewer to see and change properties of the object (top part), to see and invoke scripts for the object (bottom part), and - the main point - to add your own instance variables and your own methods to the object.
