By using the dropdown menues at the top of the panels you select which GUI and thematic map you would like to work with.
By using drag-and-drop you add themes to a specific thematic map.Click on a theme in the left panel and drag it into the right panel.
To remove a theme from a thematic map you can right-click on a theme in the right panel and then choose “Remove.”
