The next two buttons affect which controls are visible. You can choose to hide options like the Looks Panel and Side Panel to make a larger preview image.
Show/Hide Looks Panel. The Looks Panel on the bottom of the Luminar Flex workspace is where you’ll find all of your Luminar Looks. These include those created by the Luminar team as well as your own custom Luminar Looks. To hide the Looks Panel, just click the button to toggle visibility or use the Tab key to hide both the Side and Looks Panels.
Show/Hide Side Panel. The Side Panel on the right side of the Luminar Flex workspace is where you’ll find the Histogram, Layers, and Filters controls. This area is a fixed width and is always displayed on the right. To hide the Side Panel, just click the button to toggle visibility or use the Tab key to hide both the Side and Luminar Looks Panels.
Cancel and Apply Buttons
The Cancel button will return you to the host application without any changes. Pending which application you came from, the Apply button will return to the host application with your Luminar Flex processed image.
