Mark, thanks for pointing out the option of copying mouse selected parts, I can live with that for a while.

I never noticed the toolbars really, as I mostly used the program for viewing and printing downloaded ABC files - sometimes editing small things (like splitting a quarter in two eights), the biggest editing stuff was transposing to another key...

Btw., some more (Windows standard) key assignments would be nice:

Ctrl-Z for Undo
Ctrl-S for Save
Ctrl-P for Print Score
Ctrl-N for New Tune
