D# is far worse: either '9' sharps (crazy) for D# or only 3 flats for Eb. Doesn't it make sense the program would choose the enharmonic with fewer accidentals?

Of course, more tests in more keys would show whether my suggestion is correct or not.

OK. I tested on all 12 keys. The results are same.

In music theory, C# and Db chords are exactly the same thing.

In BiaB, when you enter a C#, it displays C#. When you enter a Db, it displays Db. Simple.

Then you switch to Nashville Notation. When you enter 1#, hit enter, guess what? It displays 2b instead.

BiaB is like a lame auto correction tool, trying to force to auto correct on your typos, except it changes your correct words into typos instead, and you can't turn it off. Sigh.
