I have another idea for a feature:

Display of the sensor movement: When gluing on the Spirit unit, it sometimes happens that
the unit is not completely straight, so you could at least recognise this - it is often
often only minimal deviations, which could have an unfavourable effect when flying.

In a second step, you could make the alignment adjustable (not just 0 degrees and 180 degrees for the mounting position and alignment of the unit), e.g. if you have recognised a deviation of 0.1 degrees, you could use a parameter to virtually align the unit exactly to 0 degrees again.

Best regards
