Zone levels on Map

In Classic the map fills the whole screen, but does not show the suggested zone levels (20-30, 15-30) for each zone, like some maps show (when you mouse over zones on the continent-level map).

If I turn on the addon “Leatrix Maps”, the map shows the zone levels on mouseover, but the map is no longer full-screen.

Is there a way to have both? Can I get full-screen maps that show zone levels on mousover?

It’s not for me. I’m asking for a friend…okay, the 4 or 5 alts I am playing today. The list changes daily. I’m an altoholic.
