Great job! You can hide dock and use Touch Bar instead. And get more screen space. But actually this approach is not effective for me( I need to look at touch bar and slide it to get required app. It's much more faster to click on app icon in dock.
Really great job there. Quick feedback, x and esc should be swapped cos now it's really confusing and if you guys can include active and recently open functionality it would be really awesome product. Maybe simple 1 finger double-tap or long press can be a trigger here?
