title: Set toolbar icons size in Android Studio 3.0.1
body: <p>I've just installed an update to android studio and now I see version <code>3.0.1</code>
  When I look to a toolbar I see that icons became two times smaller than usual. </p>

  <p>Is it possible to make them bigger as it was before?</p>
