This has been explained so many times:
- We cannot freely choose which key to use, we can only use what's available in the Drone camera. This because, the MSFS SDK, opposite to the P3D SDK, doesn't allow Simconnect add-ons to intercept keys, because the simulator will receive it anyway, so we had to choose something which was not too much in conflict with what the Drone camera uses.
- Contrary to P3D, there's no way to detect Mouse clicks in the 3D world, if you are not an airplane with your own cockpit.
I've had my sim setup for two years to use the arrows and num keys for moving my camera system around and I'm not about to change all of that to accommodate this antiquated editor.
When discussing UI and human interaction, everything is highly subjective, and what one finds comfortable, another one will find it a "nightmare". For me, using the arrow keys to control the camera IS the ultimate nightmare, because I'm using this:
