Users Have Different Personal Preferences

Of course, everyone has different personal preferences. Different users prefer different screen layouts, screen colors, fonts, and other options. Some users prefer to use the mouse, and others prefer the keyboard. Some prefer to use toolbars and context menus, and others prefer the menu bar. And some users are more cautious and constantly save their work, while others never save their work. If you provide users the ability to set, save, and restore their preferences, they will find using your program much more enjoyable.
