In order to improve GUI usability, the DiskSorter main GUI application provides three user-selectable GUI layouts. Press the 'Layouts'
button to switch the GUI application to the next GUI layout.
The first (default) GUI layout displays large toolbar buttons with descriptive text labels under each button and shows the directories
entry and the profiles combo box under the main toolbar.
The second GUI layout displays small toolbar buttons with descriptive text labels beside each button and shows the directories entry
and the profiles combo box under the main toolbar.
The third GUI layout displays small toolbar buttons without descriptive text labels and shows the directories entry and the profiles
combo box as a single toolbar.
