Number Notation in key other than C, Roman numerals

[SteveInChicago]

I just noticed a little workaround... with global transpose set to any other than number notation, if you change the song key to number while in play, playback does not get transposed. (until you hit replay) Please don't fix it!

No plans for roman numerals - at least at the moment (yes I am used to them also, classical, working out SATB etc.) We decided on introducing Nashville for this latest version (Mac v2, iOS v4).

May I strongly request roman numerals- it is easier make out which is the root and which is the quality when the root is in roman and the quality and/or extension is in arabic. Especially in cases like, b77 (I do imagine they are harder to implement due to the fact that there are more characters needed per chord... e.g., bVII7)
