I do see a text size and color setting in the ahqa_action_item.xml file in the RES directory, but the instructions for using this library explicitly states that these files should be set as read-only and I'd rather not mess with it without having some direction to do so. All the other xml's in this directory only have settings for left and right padding and horizontal alignment.
OK, I edited the xml file and changed android:textSize="12sp" to android:textSize="24sp", saved and set properties back to read-only, ran Tools->Clean Project and compiled. No joy...text in the menu is the same size as before.
