Hi. I find it useful to switch my computer to grayscale to minimize distractions while working. To enable this I go to System Preferences -> Accessibility -> Display, and toggle "Use grayscale".
I would really love being able to toggle Accessibility options as a "predefined action" and link it to a BTT gesture/shortcut.
See this post for a non-BTT workaround to this feature: https://discussions.apple.com/thread/8247628
Thanks and great job!
Best,
Martin
