Adding Modules to herelink

Does anyone have any experience with customizing the UI in Qgroundcontrol? Like for instance, given the small amount of buttons on the controller, it might be extremely useful to have a camera control menu on the touch screen as opposed to a tactile button. They advertise an Open API for the controller, but what does that really mean?

In addition, are there any plans to increase the channel count on the herelink? Is it possible to do, maybe by increasing the latency? Or would it need a hardware revision?

Thanks,
Martin

Have a look on our CubePilot GitHub for the QGC that is in HereLink. Feel free to adjust it to suite
