Hi everyone,

Just posting the url for this app that may be used to learn, study, preview, etc ,
things related to the guitar fretboard. From Scales, related Modes, Intervals,
add/del strings, changing tunings, etc.

It's free and available as a Google Chrome Extension at: http://bit.do/fretnotes

Nothing fancy, but it helps me so maybe it may help you too.

ps. one advantage of releasing the app as a Browser Extension is that before the
app is released for the public, the Google team checks all the coding against
any malicious code a "bad" app could have, so in sum you can install it safely.

ps. The text in the url below is what you need to know to operate the app.
