Big Screen allows lyrics in the Control Surface to be displayed in a Grid View or List View. Grid View is ideal when you want to preview exactly how your content will display on a Frontened. List View is great when you only care about the lyrics and want to fit more lyrics on your screen at once.
It is super simple to switch between these views; simply click the toggle switch in the bottom toolbar when viewing a song item.
