One common usage for pots (P1-P2-P3) is to adjust some parameter (gyro gain, a GVAR used elsewhere, or whatever). The problem is that when you change model or even just carry the radio in a bag, they might be moved. Due to this, that usage scenario is pretty much cmpromised as there's no way to mark the positions.

So... I think it would be nice to add the same thing as the switch warning but for pots. One line in the model settings where you choose for which of P1, P2 and P3 the warning must be enabled, and a "Store" item that will store the value for the selected pots when pressed. Something along the lines of Pot Warning: S 123 S is the first item so it's easily reachable to set the new setting after a flight, 123 turn normal/inverse when enter is pressed to activate the related switch or not.

On powerup, a new warning screen shows the values of the active pots and the value they should have. Current value is displayed inverse (and warning stays active) if value is more than +/- one count off the stored value. When it matches it, after some short delay (1s? the goal is not to dismiss the warning while the user is setting the pot and just "flys over" the correct value) it turns normal. When all active pots are normal, warning goes away.

This would mimic the behaviour of the mechanical trims on the MPX 4000. At startup, and when selecting a model memory, the user has to move the trim levers to their previous settings before the regular startup menu can be displayed.
