The NanoGong applet shown below does not have three of the usual components on its interface. They are the save button, speed buttons and the audio level indicator. Hiding of any these components (also the record button) can be achieved by setting the corresponding applet parameters. The color of the applet is changed using the color applet parameter. The time display is enabled and will be shown if you hold your mouse over the timeline.
