To see it, start a new song (key of C), and enter a G chord at bar 1, then go to save the song - BB will issue a flash message "Key is set to C, but key signature should likely be G based on the chords". If this message appeared too often, people might get annoyed, but yes there are probably improvements that could be made.

Thanks for your reply Andrew.
BIAB is a very intelligent program right now.
It knows its chords.

I don't think it's a good idea to remind or prompt a user at the time they are saving their song.
That could happen after some time and possibly frustration too.

With BIAB's vast knowledge of chord progressions and keys it can probably figure out the key of a song after just a few chords are typed in.

When it is confident it knows the key and sees that the Key at the top of the page does not
match it should immediately put out a pop-up to that effect, alerting the user. Possibly even stating that not correcting the Key could lead to weird-sounding chords.
