Matt:

As per my post, these settings are found on the "Views" portion of the menu bar, under "Chord Display". When you click the down arrow there, right at the top of the ensuing list is a an entry called "Layers".

If I use the flyout and select (say) "Normal" under the "Additional Chord Display" heading, the chord grid will now display the "regular chords" plus an area above each chord for the "Additional" chords (say) Nashville Notation.

That same dropdown contains (at the bottom of the list) a "Visual Transpose (any amount)" selection. (There are also lots of other "transpose" options there.)

Then when I'm finished my work session, if I've used either or both of those functions, BIAB "remembers" them when I open up a new session, rather than returning to a default of "not" showing them.

Thanks!
