Tap on chord to show name in other font/system

The Jazz 1350 version of Darktown Strutters Ball still has an old error. Incorrect use of a coda symbol to try to indicate the end position causes the tune to repeat before reaching the last few measures. I’ve edited my own copy and used slightly more standard chords. Do you want my update? If so how do I submit it? Thanks.

Currently, tap-and-hold on a chord does nothing. I would love to be able to tap on a chord to show (if in default font) the numeric chord representation or (if in numeric font) the actual chord name in the current transposition. Every now and then I have a brain cramp and want to confirm that it’s a C#13 rather than a C13; or I wonder what role that C# has. BTW if the settings screen said “font/system” rather than just “font” this would avoid some learning curve confusion. It’s not intuitive to use “font” to switch to numeric notation.
