Fixed tab strips, toggles and list cards on a phone
Between a phone and a laptop, a page with many tabs hid its last tabs beyond the screen's edge; the strips now scroll sideways as soon as the side menu folds. On a phone, the on/off toggles (the account settings, the notification settings) answer a tap just above or below them, as a finger lands, and the row cards of a list inside a card keep a small gutter from that card's border instead of drawing a doubled line against it.
