Looks pretty, but you need to simplify the experience:<p>99% of us play ONLY standard tuning. So give us the EADGBE notes as the default and please don't make choose from 12 notes. Guitar players rarely tune to C# or Eb.<p>Also, "4th Octave C" is an accurate but not a useful description for guitarists. (It is, to pianists). We just need to know "High E or Low E".
