If the AUTO PID makes troubles, it needs several mouse clicks to stop it. Please make an emergency button, so that only 1 click is enough to stop the procedure and switch the motors off!

And please change the arrangement of the graphical "instruments". All settings are in the order
1.) ROLL
2.) PITCH
3.) YAW
but the three "instruments" are in the order
1.) YAW
2.) ROLL
3.) PITCH
I want to recommend to move the YAW "instrument" down where also the YAW motor is located.
