The New Quiz tray does not use standardised icons, has no mouse over text, and clicking instructions does not lunch instruction editing (Mac Safari in edit mode). This means the tray's functions are not immediately evident when used by new users.
Have tray open by default. The first item could then have, click to minimise. Standardise the icons. The icon to open the tray is the universal Tab icon. Consider using > or similar. All icons should have mouse hover text to provide context. Clicking the Instructions icon whilst using Safari on a Mac should take the user directly to the instruction edit screen (like it does for other browsers)
