I started seeing the TB as a missed opportunity for a second screen but with the Golden Chaos touchbar replacement (a preset for Better Touch Tools) I see it as my computer's Apple Watch The touchbar is totally under-utilized by Apple. Golden Chaos demonstrates that it just needs a new and appropriate sign language and immediately gets much more useful. With Golden Chaos I use my touchbar to see my current email count, whats playing plus media controls, calender, time, weather, battery – and if I press a modifier key a whole universe of shortcuts opens up. My only addition - and the most heavily used function - is a button to push my current window to the other monitor. So my touchbar effectively is my tool to utilize my second screen more easily.
