Allow this thread to serve as a way to send DJi new ideas for their modular gimbal. I'm excited about all the possibilities.
I'll start it off:

1. One or Two (minimum pitch) axis bright LED search light

2. Three axis camera with better camera sensor.

3. Three axis camera with some zoom capibility. Opitcal would be great but I know that wud be challenging for this platform so I'd settle for digital.

I agree that a zoom would be nice but that is another control to deal with. Could be problematic for a single operator to pan/zoom/fly at the same time.  A simpler solution would be for choice of longer prime lenses. Maybe in the 60mm range 100mm range.

Better sensor with more still photo resolution.
