We've finally made progress in a basic feature we said we'd implement: user-selectable waveforms! Check out the work-in-progress PR here: https://codeberg.org/tenacityteam/tenacity/pulls/793
What remains to be done is if there's anything we should further include for better backwards compatibility with Audacity (3.x). Right now, custom waveform colors in Tenacity will not be shown in Audacity, and vice versa.
