There's a lot I don't know about music theory. When I see something like C/E, I assume we are talking about a slash chord (https://en.wikipedia.org/wiki/Slash_chord) in regards to a txt or ChordPro file, which just changes the bass note. If you have a proposed algorithm or method for handling transposing that works for any scenario, please send it my way and I'll be happy to review it and make changes if needed. Does the main ChordPro application handle whatever it is you are wanting?

In regards to the initial post, the key of F uses flats, not sharps. So the algorithm defaults to using flats for tranposing chords. There have been many conversations over the years about how transposing is handle in MobileSheets, and the current implementation is what was developed based on feedback from many people. No one else has complained about it or said it works incorrectly. You are the first to do so in a long time. I'm not saying you are wrong - but I need to hear more feedback and receive more information about how the implementation needs to change to match what you are wanting. I should also add that transposing in the editor may work differently from transposing when just viewing the score normally, which is why I suggested you might want to try that to see if it helps you get the result you want.

I do agree that you are being quite aggressive and impolite though. I do want to help you, so I wish you wouldn't assume bad intent.
