We discussed the use of a group pointer in a shared editor with a shared view. Consider the advantages and problems of using a group pointer when participants have different views. How do you show the pointer if it is outside part of the document you are working on? Think also about the issues when the system is a hypertext-based co-authoring system. Is there any use for a group pointer in this case?
