Huge fan of your touchbar!
I am a medical student in the U.S., and like many other medical students I rely heavily on a flash card-based application called Anki. If you are looking to add more features for the TouchBar, I was hoping you would consider looking into making a Dock Badge for the application with a marker for the amount of cards still left in the deck.
Additionally, I have been working on a BTT Touchbar that is app-specific for the program, but I am by no means a coder and it is quite terrible. I was curious if you would be interested in making an app-specific aspect as well. If you would take on this task, I would be more than happy to help you with what would be useful on the TouchBar. I think you can get A TON of medical students to download this Touchbar just for the Anki-specific features.
Thanks again for making such a great tool! I use it everyday.
