some ideas,
trying to do them but I'm a not a programmer... it will take time
add somes silders for :
vbatscale (trying to do this here :
viewtopic.php?f=7&t=974 you said it's easy....

)
and boxes to enter batteries alarm levels.
minthrotlle/maxthrottle values
deadband.
add more states options for aux and extra sensors I think's 3 (low,mid,high) it's not enough with a good radio you can configure 6 states with 2 buttons.
an automatical start when comX is selected, a gui restart button.
sending datas to a txt/cvs file.
change value colors when acc/gyro/mag/etc... are positives.
a few checkbox to swap gyro,acc,mag roll(x)/pitch(y)/Z. when sensors are not in the right way, for exemple on my hexa allinone is 90° counterclocked(X become Y) and another checkbox to inverse those values Y->-Y
a "magical formula" to compensate not well oriented sensors, when I tilt perfectly my mwc to forward(pitch up,positive) some "roll" values appear, because my sensors are not well "scotched".
a checkbox to test motors at
very very low rpms .. Beginner doesn't (often) connect the right esc to the right motor connector's.
a secure button to not arm motors when you play with your mwc on your desktop.
