Wire frame: Display the object with the wire frames on.

Canvas: Show or hide the Grease Pencil canvas. The Default is "show".

Uniform Stroke Thickness: Disable Pen pressure effect from the strokes.
Origin To Center: Because the carved object needs to be at the global center, it will be automatically translated there every time you activate the add on. This can be undesirable at times so when the button is pressed the object origin will be translated to the global center, instead of moving the object itself.
Material Assign: When on, all newly created geometry will be assigned a random or user defined material.
Random Material: Toggle between randomly assigned material or user defined material. When off, it will display a color picker to allow the user to choose a custom color.
 
Mute: Mute all operations temporarily (like undo), allowing you to make changes to your Grease Pencil lines. After you are done with the lines un-mute to see the updated version of your object instantly.
