Add option to turn off the dictionary description box on clicking it

(Describe the feature or change)
Some of us use the JPMN handlebar to export dictionaries and the blackbox is visually in the way so I think it's a good idea to have an option to turn it off

it's as easy as a CSS flag like this:
.content-footer {
display: none;
}
so I think it's possible to add a GUI ontop of this option
