Emisar d4v2 aux led mode

Would love to have an option for aux LEDs to fade on and off “ramp” instead of the flash low flash high mode

That’s not possible with the hardware. They would consume the same power as keeping the main emitters switched on.

What about the options where the aux led change color instead of switching to next color it fades to the next color ?

That might be possible with some effort, but each transition would consume 100% CPU (software PWM).
