Guitar slide needs src and dest fingerings to show

I use workarounds in 2 ways …

  1. Click the ‘slide in’ box on the note that needs the slide

then select a close earlier note - higher or lower to suite the slide direction - and then check these 2 notes use the same string.

  1. add a solid line (note to note at the top of the panel) from the lines panel joining the 2 notes and adjust angle and length in Engrave mode.
