This video will explain the Interface view and the different function
Below you can see the naming of the different sectors in the interface view, the ribbon in the top of the view has the print option for labels on the keypads, insertion of images, text, symbols and shapes.
The Interfaces box allows you to switch between the different connected expansions e.g. another EcHo Plus panel or a NEB keypad.
In the Graphical elements underneath, you will find loads of elements, but mostly for UI's on the Touch Panel. However, there are well designed labels for EU and DK/US keypads here also.
On the right hand side, you will find the properties for the selected elements selected in the middle window.
