• At the top right are the controls to change the musical pitch and the number of decimal places displayed.
• Selecting two boxes in the table shows the difference between the two values in the Diff section, located on the right.
• At the top left is the information popup button. When activated, hovering the mouse cursor over the table displays a popup with the name of the corresponding note.
