The average person cannot write good documentation (or website copy). It's an actual skill to learn how to phrase things, ensure that the documentation delivers the right level of detail to the different reader types etc.
As English writers, software developers make great programmers, not authors.
> A background watcher reads the foreground app's identifier once per second; when it changes, the overlay you authored for that app is layered on top of the device's global bindings, with per-app entries winning and any unlisted button falling through to the global map.
as is in the documentation right now could have just read
> Your device will automatically use app-specific keybinds when a given app is in focus.
So much of the documentation copy especially is typical of the ways LLMs leak implementation instructions into their written copy.
