There’s only one dev whose lack of support matters — Apple.
I’m in the minority that have a very real use for Fn keys. I still use a (5250) terminal emulator daily for work. But… when I’m working, I’m at my desk, and when I’m at my desk I have an external keyboard.
I never understood it. I understand when, for example, ATP talk about how Apple never went anywhere with it, and that that is probably a very good reason that it will be going away soon, but that isn’t really a reason not to use it, such as it exists. It’s more than just group think… I also think it’s a bit of “I don’t want to get used to something if they’re going to take it away.” Except many have been worried about its imminent demise for more years than they keep any computer.
So… just like tiny buttons on a menu bar then? More than half of the right side content of my menu bar is visual information. I can see my local weather conditions, my Bluetooth peripheral battery levels, my computer’s vital signs, how long until my next break, and the date and time. As a (very) recent convert to BTT, guess what I’m using the left side of my Touch Bar for.
Also… I’ve heard many people say they prefer the media keys to the Touch Bar. I’m firmly in the opposite camp. I have media keys on my Apple Extended keyboard and every single time I want to mute my audio, I have to stare at the keys to find the right one. By contrast, the Touch Bar mute button not only is easy to see, with no ‘F10’ legend cluttering it and wide spacing from its nearest neighbour, it also shows the current state.
