> reader view (not sure if chrome has that out of the box nowadays) As far as I can tell, Firefox, Safari and Edge all seem to have it, and Chrome does not. Not on mobile, and not on desktop. There are some extensions that accomplish the same. I've had some good (but very limited) experience using Mercury Viewer some time ago: https://chrome.google.com/webstore/detail/mercury-reader/okn...
I think Chrome does have it on mobile, because it prompts me to "reader view" a page when it isn't properly formatted for reading, on Android 7.
I would still argue that its function is different than the "reader view" functions of other browsers, but it does have it.
