gmail had a kind of hidden option for adding keyboard shortcuts and their labs options. Not really a fully different interface but for a long time they kept that pretty lively.

Unfortunately gmail has fallen off pretty hard lately. I can't even reliably expect my attachments to actually send the past few weeks.

email still has non-marginal-interfaces available in general though.

You can still configure some combination of mutt, offlineimap, sendmail, etc to work with gmail and view your emails locally in a proper viewer.

Or use thunderbird I guess, though thunderbird feels pretty "marginal user" focused compared to mutt.
