It’s got a compact view that is pretty much why I’d be using if I started. I think it makes sense to default to the “cozy” view, even if that is the most bass ackwards naming I’ve seen. The reason being is that “most” people prefer that view and are the same people that wouldn’t bother looking for a setting to change, they’d just nope on out because they got overwhelmed.

Default “cozy” in desktop mode

“compact” in desktop mode

I think compact looks decent in mobile view as well, but since the parent post is about desktop UI that’s what I’m showing.

I’m pretty sure “apple mail” refers to the Mail app on iPhones and Macs, not the email address. There’s probably tons of people using Gmail addresses with the Apple Mail app.
