Instructions
Start the Dominoes program and click on the "Configuration Mode" button in the top menu to begin editing.
Right click on the bar you want to hide from view to open up a drop-down editing menu. Scroll down to the "Show States" button.
Click the "Edit" button to open up a text box. Enter the phrase "never" in brackets.
Press the "OK" button by clicking on it with your mouse. Edit any of the other bars in the game this way to hide as many as you like.
Re-enter the configuration mode at any time to display your bars again. Follow the same process but delete "[never]" from the text box to make your bars appear at all times.
