When iReal Book returns, as I have no doubt it will, it would be nice to have a feature where you can flip a page so, instead of seeing chords notated in the standard Arabic alphabet, e.g., Cm7, Eb, Gm, etc. it would be displayed in Roman numerals, e.g., II-V-I, or I-VI-II-V, etc. Of course it has to be linked to the correct key for the chord sequence. In fact, this feature may already be built in, but I just haven't found it. Suggestions anyone?
