Topic: I have a suggestion that may be useful.
First off, I have to say I absolutely love this site. Thanks for making such a fantastic resource free. The chord transposer is just beyond useful. Anyway, my post has something to do with the transposer in kind of a weird way. Generally, when I look up a song I will transpose it to a few different tunings to see what one fits my voice the best, then I will add it to my songbook. Well, here is the suggestion.
Sometimes, after adding the song to the songbook, I will decide that another tuning actually works a bit better. My suggestion is to add a button that allows you to "Update song with current tuning". I think this would be extremely useful.
Thanks, and keep up the FANTASTIC work.
