Booth Themes require Darkroom Booth 3.0.777 or higher.
Here is a sample template to help you get started with some of the features in Booth 3.
This screen template file should be extracted and saved in X:\Booth Screens
When you select the template it will ask "Would you like to load the settings from the screen template?"
Click "New Event" to avoid overriding the settings on the selected event.
