Hi Aaron,

still on the journey to understand all subtleties of your code...

One detail: meanwhile I don't think it's nice hardcoding the
font-size, looks bad for high or low staff-spaces.

How about looking at staff-space and derive a suitable value from it?
I.e. in `curve-adjusted-arrow-head´:

[...]
      (let* ((staff-space (ly:staff-symbol-staff-space curve))
             ;; reducing fs-from-staff-space a bit looks nicer
             (fs-from-staff-space (1- (magnification->font-size staff-space)))
             (grob-font
               (ly:paper-get-font
                 (ly:grob-layout curve)
                 `(((font-encoding . fetaMusic)
                    (font-size . ,fs-from-staff-space)))))
[...]

Best,
