The features of X Buttons are:
a. Several buttons are grouped into a theme. Buttons are easily added or removed from themes
b. Themes are either in exclusive or non-exclusive mode. In exclusive mode, only one button is turned on at any one time. For non-exclusive mode, any number of buttons can be turned-on or turned-off
c. Buttons in a theme have either two or three states. A two-state button toggles between red and green and a three-state button toggles between red, orange and green
d. Several themes can be loaded simultaneously. Thus, buttons with differing properties can be loaded into the same screen
e. Display timestamp of last use on buttons
f. Customize names and descriptions of buttons or themes
