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 default GUI layout displays large toolbar buttons with descriptive text labels under each button, shows the right side-bar with
multiple tool panes, shows the main file classification results view in the middle and shows the file categories and filters view on the bottom.
The second GUI layout displays small toolbar buttons with descriptive text labels beside each button and hides the right side-bar. The third GUI
layout is a minimalist layout, which displays small toolbar buttons without descriptive text labels and hides both the right side-bar and the
bottom file categories and filters.
