When starting the program the user will get a menu bar that contains a number of menu-options in the upper part of the window, and directly beneath these options there is a toolbar with a number of buttons for various shortcuts.

On the title bar the user will see program name (Settlement), project name (this is decided in Title), current file (* if not Save as has been used) and active window.

During the usage a number of windows will pop up showing the input and results.
