The Appearance Options dialog sets preferences for the overall appearance of Liquib.  The default Liquib interface, with colors on a dark background, can be difficult to see on some monitors, or even hard on the eyes.  (And some people just don't like it!)  In such cases, the Interface Style can be switched to Standard Windows, which provides a more conventional appearance.  A Use Large Cursors option is available for people who prefer bigger cursors to represent the currently active Tool or Effect.  A Background Color can be chosen for the screen area where images are displayed.
