So-called hamburger menus. New Relic has oh so helpfully moved everything useful into a hamburger menu it took ages to find (it even turns into a picture of a hamburger bun when you hover), while useless trivial distinctions get giant, labeled dropdown menus. The affordances are all backward. But I bet everybody clicking around looking for the features they used to use showed more "engagement" with the site, right?
The gmail app still allows you to use a list to select different accounts (tap on the account name).
