Please default to flat keys when modulating on practice mode.

Context: I know that choosing flat chords over sharp when transposing has been discussed and that there's complexity around transposition. But I'm just talking about practice mode which modulates up a set number of steps each round. This routinely puts me in keys like A#. I think most of the users of the app are jazz musicians like me who never think of songs in Bb as being in A#.

I'd at love to have the option to default to flat keys wherever possible.
