Would it be possible to introduce a setting that would cause the chord diagrams to be, say, those closest to a targeted fret? For example, the user could select Fret 6 (say), so that chord inversions closest the 6th fret would be shown by default.

I know it is possible to change chord diagrams one by one, but the default is now fret zero (open position). Seems like it would be straightforward to move the default "base" fret up the neck.
