Hi all, I’ve edited many of the chory sumbols to be slightly smaller than the default. (maj 7 triangle and augmented “+” for one. i have them around 80% or less, typically, in the default chord symbol editor:
I believe you have only edited the Fmaj7 chord symbol individually. To globally scale down the size of the triangle used in all maj7 chord symbols, you need to edit that component only. Click the big triangle we see in the chord symbol editor, then click the pencil to edit just that component.
