Google finally added an preference setting that provides a reasonably sized compose window, but (presumably) in keeping with their new interface guidelines, it&#x27;s well hidden to prevent accidental discovery.<p>To change it, you need to open a compose window and click on the &quot;down arrow&quot; in the lower right corner.  You can then choose the option &quot;Default to full screen&quot;. It still pretends to be a pop-up window, but it&#x27;s large enough for real use.<p>Arguably, this is a reasonable place to put this setting:  it affects only the compose window, so the setting is only accessible from the compose  window.  But personally I never would have found it without searching the web for a solution.
