For example, when I open iTerm I have buttons for my local development env (DB, redis, api, frontend, various microservices) color-coded by status and can start/stop them by tapping a button. You c…
Nothing you describe relies on touchbar, only Fn keys
Are you old enough to remember when PC applications came with templates that fit over a 101 key keyboard to show you what all the fn keys did?
