Icons are ambiguous. Everybody violates expectations about what an image does. The older UIs had text. More than that, settings was a folder just like every other folder, so you knew what would happen if you clicked on particular section. Things were fairly unified, even though the standards didn't integrate everything. You knew what would open a new dropdown, and what would open a new window, at a glance. There was no need of any implicit knowledge.
