Brendan Le Glaunec also inspired another person to develop a pretty great set of Touch Bar controls for BTT available here: https://community.folivora.ai/t/goldenchaos-btt-a-complete-touch-bar-ui-replacement-preset/1281
I was just able to download it and get it running in about 10 minutes. It takes a little time to understand the groupings, the modifier keys, and the settings, but once you do, oh boy. You can modify it to fit your workflows. I took out the reminders bit and replaced it with OmniFocus. I plan to do something similar with the calendar.
