That spacer still activates the 'ESC' key
Personally, if I make the purchase, I will probably just remap the Caps Lock key to ESC - assuming I can remove ESC from the Touch Bar.
The one thing I didn't care for is that the Touch Bar display can time out. I would personally prefer that it stay on - or at least have the option of it staying on.
The timeout implementation could definitely be improved. In 6 months I've hat that computer I've never had it be a problem or even found it annoying in any way though.
