* The graphical user interface (GUI) works by splitting the screen in

* The general screen layout is composed by an upper status bar at the

* top of the screen and a lower status bar at the bottom.
|
|
* The central portion of the screen is filled by two big text/number rows
|
|
* And a small row.

* Below is shown the row height for two common display densities.
