1) Visualization of the sticks position on the screen during the flight. I have already supported this request of one of your clients in the topic https://itch.io/t/173216/stick-indicators
2) Assigning the "low/high rates" option to a keyboard shortcut. This has already been discussed here https://itch.io/t/19821/how-to-fly-a-fpv-quadcopter-racing-drone I even asked to leave this option and not remove it. ;)
3) And finally, in the readings of all parameters in the settings, make a window with numbers, and on the right - up/down arrows. Something like this...
It will be easier to assign a digital value: without moving the slider, but by clicking on the arrows, or directly entering the desired number from the keyboard in the window.
Best regards, Dan.
