How user interfaces should be like.

... Computer users should be able to access their most frequently used screen immediately, and perform routine tasks without changing screens and with a minimum of keystrokes. The system should also lead the user through the logical sequence of operations. Once a computer has been informed of the item code being worked on, it should retain that code and not require its re-entry. Data that are already on file should, of course, be accessed by the system and should not need to be entered again once the initial information has been established.
