Hey there,
I was looking through your chord finder a while back and never got round to letting you know. There is a mistake on the C7#9b5 chord. All the diagrams have a b9 instead of #9 and a #5 instead of a b5. I think maybe the title of the chord is wrong as opposed to the diagram. It's the one straight underneath major.
