@d-healey Mainly because the default method of showing the octave numbers doesn't really work for small and large key sizes, but also partly to avoid using LAF. 😜
Since I know I'll want control over octave numbers in every plugin I create - and I probably won't want to override anything else about the already-very-nice-looking keyboard - it made sense to me to bake it into HISE rather than using LAF every time.
