CUSTOM VISUALIZATIONS IN TAB GROUPS

A multi-document application that includes a multi-document interface that includes a view area that displays one document at a time and includes a tab group element that displays tabs, each tab having a control that permits a corresponding document to be visualized in the view area. When a new document is opened in the multi-document application, the multi-document interface adds a new tab to the tab group element to represent the newly opened document. The color coding of the tabs and/or the tab sizing is configurable by a user rather than being predetermined. Other visual properties may also be configurable.
