Hello!
Thank you for developing TuxGuitar! I'm very happy to use it to make my own arrangements for classical guitar. But the only one additional thing is needed - support of more than 2 voices for a track (3 would be enough for most compositions, I think). If you will add this feature, it would be great.
I second this. It is the only thing I miss so far.
Sometimes you need to have a bass string hold for the whole measure, play a melody in the top string, and have some chords on the middle strings. That requires 3 voices to notate properly.
