By pressing the minimise/maximise icon in the toolbar, you can toggle between the full view and the compact view. Once you have set up your headphones and selected the room type, you can switch to the compact view for a cleaner workflow.
In the compact view, you can quickly switch the loudspeaker emulation ON to hear how your mix sounds on a loudspeaker setup, or OFF to hear how it sounds on typical stereo headphones.
There is a level meter with a clip indicator integrated as well.
