The official firmware can be better beacause this TX can do mutch more if someone can mod this firmware.

-all channels info in one screen
-mode for crawler to select with one button front,rear, crab and 4ws steer
-more mixing options
-more channels
-for rc3s compatibility with Gyro RX
-enable/dissable sound
-Adjustable Backlight timer
-Inactivity Alarm
-ST and TH Dead Zone
-Channel Speed (All Channels)
-Dual ESC Mixing and steering
-Multi Position Switches
-Key Mapping
-Sub trims
-Adjustable long press delay

Well something like gt3s if is it possible. And there are more peope out there who want this mod.

Kind regards
