Another feature that people sometimes ask for is the ability to collapse comments into small objects, that can be expanded by the user when they want to read the whole comment.
A related feature is the ability for the user to resize a comment without changing the text.
Both features are implemented by the ResizableComment example class in Demo1. The following screenshot shows two ResizableComments. The one on the left is expanded and selected, with resize handles visible. The one on the right was collapsed by the user.
