Option to hide heading/caption of maps

What about having an option to hide a map's heading/caption on screen level (probably on map level as well)?

Currently one might have to arrange objects in maps around the heading (when wanting to avoid a bad look).
That may lead to a lot of wasted space on screens having several map objects and/or maps with long names.

The attached image shows a part of a map where every vertical pixel counts thus positioning of objects below the heading is no option - beside the fact that in this context a heading is not needed / not of additional information at all.
