Diagram sheets come in four visual styles:
- FBK — the orange-and-tan house style.
- Looking Glass — classic black-on-white with finger numbers, ×/○ markers,
and barre arcs.
- Motion — clean opaque dots with bold labels.
- Motion Split — like Motion, but shared tones in polychords render as
split half-circles.
Pick a style from the toolbar; the whole sheet (and every export) follows it.
