Gmail Icons are Hard
I've said it over and over again:<p>I speak english, not pictogram.  The only platform I've ever seen that got icons right was Windows Phone, because it had a hard-coded "..." button that always did the same thing:<p>1) Show all the labels, and<p>2) Show all the additional text-labeled (non-icon) actions that were hidden by default.<p>So the first thing you did when faced with an unfamiliar set of icons was touch the "..." button which showed you the full list of things you could do.
