The LAYERS view provides the names and a visual representation of the Waveforms or Soundsources that make up the Patch, along with Volume faders for each Layer.
You can click on the Layer labels (A / B C / D) to turn that Layer ON / OFF.

Clicking on the waveform image opens the waveform menu. The stepper arrows allow you to step through Waveforms or Soundsources, and for Layers that use Soundsources. Clicking on the image takes you to the Soundsource Browser and the magnifying glass takes you to the Soundsource Zoom for that Layer.
