One thing I haven’t seen answered is whether app controls (like iTunes play / pause) can be “pinned” to the touch bar regardless of the current app. I’d also like to be able to show something like a progress bar for one app in the background, say rendering a video, while I’m doing something else like browsing the web. Is this supported?
Also two fingers + thumb for right click (is this not the default?) seems much more natural than either of the methods you mentioned, once you get used to it. Works wherever your fingers already are.
