Sketch Palette: a right-aligned control column, one Look At icon, a disclosure triangle, plain-noun labels (#497)

Every Options row puts its control in one right-aligned column, Look At is a single label with an icon button, Options folds with a disclosure triangle, and the toggles use plain nouns (with dedicated ids for Profile and Points so they don't collide with other labels).
