What does usability even mean? It must work effective, efficient and satisfying.
What is the use if the Application can do many things but nobody understands how results are achieved? The Application should do only one thing tailored to the specific need. Communication between Software and humans should be as simple as possible.

Today we are already confronted with to many problems. Software should’t add to this. Working with an application should be fun.
