FileMaker solutions can live and die by the interface alone. It’s the first thing a user sees and can sway their opinion in the first few seconds of them seeing it for the first time. It’s so important but many developers don’t give it much thought. How do you develop an interface that clients want to use and which makes it easy for them to do their job? Do you use a standard theme or do you take the time and trouble to develop a custom theme that you can use over and over again? How do you size the screens? How much color should you use? How do you take into account that some of your users may be color blind? These and more points are considered to give you a well rounded look at interface design.
