Add menu items to the popup menu on the Content Pane tabs. These items let you toggle the orientation of the tabs, set their display contents, change the insertion position for newly opened files (in JBuilder 6 and up), and alter the tab layout policy (in JBuilder 8 and up).
To install, just copy the JAR file to the JBuilder/lib/ext directory and restart JBuilder.
