SHORELINE - This setting chooses the level of "natural" terrain effects.
"Random" - DEFAULT - 40% chance of "Natural", 30% "Pressed", 30% "Solid".
"Natural" - Creates a solid core, then adds four to seven "subcontinental" regions which can vary in shape and size, or even be a small island chain. These often reach out in to the sea, forming snaky peninsulas or occupying a "corner" of the main continent with a fat, unpredictable protrusion.
"Pressed" - Creates a solid core, then adds two to four "larger" subcontinents. This setting also shifts more to the north or south, at random.
"Solid" - Nothing but the solid core, larger and with smoother shorelines.
