I'd like to see a way to create custom layouts for the Z-3 display. Either by having a small GUI where you can drag and drop different elements, such as placeholders for CAM data, text, progress bars, etc, into a circle and arrange them freely. Elements should be resizable and UI stuff like percentage bars would need a numerical source value as well as min/max settings.
Another way would be to use a simple markup language, with tags for all the data and graphical elements and some way to set position, alignment, size, color, etc.
Or much more straight forward, just let us set an image that is reloaded/refreshed every x seconds or if the file gets updated. This allows us to develop custom solutions to dynamically present our desired content on the display.
