VIRTUAL WORKSPACE VIEWPORT LOCATION MARKERS IN COLLABORATION SYSTEMS
A collaboration system can be configured to support a large number of active clients in a workspace where the workspace is distributed into disparate groups of objects. While participating in the workspace, a first active client can display and search a list of location markers, and in response to selection of location markers, update their viewport to the location of a selected marker, without changing a zoom level. The system can be configured so that active clients are informed of creation and movement of location markers.
