What's odd, is apple was all in on the touchbar back in 2016, but since then nothing has been done.
Since the Touch Bar's inclusion in 2016, they have
- Added support for TrueTone on the 2018 MBPs (on the hardware-side of things),
- Added support for Automator shortcuts in Mojave (making neat shortcuts like switching between light/dark mode and other settings and quick actions achievable in just 1-2 taps from wherever you are without leaving the app),
- Given some additional tools to developers for the Touch Bar in Mojave,
- Added Touch Bar support for the new Command + Shift + 5 screenshot tool in Mojave; not only does it give you some useful buttons but what I find most useful about this is that the Touch Bar shows the current file size of a recording
while making a screen recording so you know how much space the recording up to this point will take, something that is currently not visible on-screen in any way,
- Added support for the new post-editing tool for screenshots/screen recordings in Mojave,
- Added support for the new QuickLook editing options in Mojave,
And probably more that I'm missing. I agree that there is still a lot of untapped potential for the Touch Bar on the software- (and hardware-)side of things, but this isn't exactly what I would call "nothing has been done". Apple is definitely improving it and I don't expect them to drop it anytime soon.
It's still a bit of a mystery where they'll go with it on the hardware-side of things though, that's true. Will an external keyboard with Touch Bar + Touch ID like described in their patent from last year ever see the light of day? If so, maybe with next week's refresh? I'm not holding my breath for it, but if Apple fully commits to the Touch Bar then they'd eventually have to, and a Mac-focused Apple event seems like a great opportunity for an announcement like this, so who knows. Is the non-TB MacBook Pro really dead or was it just "merged" with the upcoming new MacBook (Air)s? Will the Touch Bar come to the nonTB-MacBooks aswell eventually?
