Another little thing I noticed today:
I needed to attach verse 2 and 3 to the tenor line to get extender lines, and by default they appear below the stave. So I switched them to above, however I notice that the Y offset box does not populate correctly, and thus I cannot make a micro-adjustment that would require a fraction between the current default alt+arrow nudge amount. I can move the orange lyric up and down until the cows come home but the Y value never populates.
