Option to represent minor chords only by the lower case letter, i.e. E minor as 'e'

Your idea

At least in german lead sheet collections it is very common to represent minor chords only by the lower case letter, i.e. E minor as 'e'.
One can nearly create the typical German lead sheet by going through:

Format > Style > Chord symbols

and selecting "Full German" (changes B7 to H7 and F# to Fis)
as well as "Lower case minor chords" (Em to em).

I suggest this second option could be augmented by the option to select whether one wants the 'm' to be displayed or not.

Problem to be solved

The 'm's as redundant information for minor chords, when they are already written as 'a' and 'e' (in lower case letters), could be hidden. These 'm's are uncommen and distracting in German style lead sheet collections.

Start in Format > Style > Chord symbols and inspect the existing “Lower case minor chords” option and the chord-symbol formatting path. Trace how minor chord names are rendered, then add the requested choice for displaying or hiding the “m”; done means German-style lowercase minor chords can be shown without the suffix while existing formats remain unchanged.
