The application settings can be adjusted through the Settings menu. This has menu items for increasing or decreasing the font size (Settings➜Increase Font Size or Settings➜Decrease Font Size), setting the dry run mode (Settings➜Dry Run Mode) or open the Preferences dialog window (Settings➜Edit Properties). Note that the dry run mode is the only setting that isn't remembered the next time you run MakeGlossariesGUI.

The Preferences dialog has four tabs: Start Up Directory, Diagnostics, Applications and GUI.
