M.Ted - Pull down the View menu and select "Split screen mode." It will give you three windows in one - the top is standard notation of the selected tune, the middle is the current tune in ABD, and the bottom is an index of tunes in the file. You can edit the ABC in the middle window and the notation will update immediately to reflect your changes. I love Barfly and use it to do all my notation any more. I also use abc4mac to produce postscript and MIDI files from ABC files. I can then pull the postscript file into Adobe Illustrator and clean it up, add additional lyrics, etc. to make a professional looking piece of music. Any more questions about Barfly, let me know and I'll try to answer them. Have fun!
