• Show timer on touch bar
• Change slide through touch bar directly

Thanks for the ideas 👍 Unfortunately I don't have a MacBook with touch bar so I'm not sure how easily I can work on this. If anyone lese could help out that would be great.

I think there is a touch bar simulator in Xcode for developers who don't have a MacBook with touch bar !
