You guys recognize that there are many tunings and you display them at the top of the tab – that’s great. But it seems like you could EASILY turn that display into a tuner. Just make it so that when I click on a string, it plays (and holds) the tone. Then I could easily tune my guitar to this by ear. If you could make a fancy tuner that listend to my guitar and showed a meter, that would be AWESOME!! But I can see how it might be difficult too… However giving me a reference note (or 6) to tune by would be totally easy and totally invaluable.
