Notice that the Debug and Variables views only display information while a pluglet launch is running. The debugger automatically connects and disconnects from the target before and after a pluglet launch. While not connected, you can switch back to the target workbench and launch pluglets from the target workbench without interacting with the debugger; for example, without hitting any breakpoints.
You can leave the debugger workbench running. Because the debugger workbench automatically disconnects from the target workbench when you are done with debugging a pluglet, you can leave the debugger workbench up and just switch back to your target workbench to continue working there. This way, you can avoid the overhead of relaunching the debugger workbench the next time you want to debug a pluglet launch.
To debug or edit a different pluglet, you can switch to the Java perspective and open it from the Package Explorer view, or you can open the Package Explorer view in the Debug perspective.
When you shut down the target workbench, the debugger workbench is automatically shut down.
