An interface can be thought of as a contract between the system and the environment. We've put together the following animation to illustrate one alternative design: The alternative offers a number of important advantages over the existing design: Option categories are presented in a consistent order The selection of one category does not alter the order of the others User has keyboard access to switch categories The use of distracting colors has been eliminated The use of distrating images on the tab headings and on the tabs themselves have been eliminated The use of embedded tabs has been eliminated While it is our belief that the proliferation of configuration options in MultiEdit has far exceeded the point of diminishing returns, the alternative design offers one important additional benefit: Additional categories can be added without impacting the design of the form or the user's ability to locate a category The result is a cleaner, more parsimonious dialog in which the user can much more rapidly locate and navigate to the information of interest. Patterns, and Java, 3rd Edition, Prentice Hall, 2010. Was that an error? Try to read the text in the image, and note the intense effort required.

We've come up with a new rule for program developers: You must at least LOOK at your designs before inflicting them onto your users. The likely result of this misimplementation is that the user will conclude the computer has yet again locked-up, and will perform a three-finger salute to get back to work. This rule is so ingrained that the phrase "Cut and Paste" could be considered a cultural archetype: almost everyone over the age of four knows what it means. Engineering is the process of designing and constructing something which assists a particular purpose and seeks a cost-effective solution to issues. An interface specification is a statement of what an architect chooses to make known about an element in order for other entities to interact or communicate with it.
