I dont think "Multi field" means anything to authors. Also, im not sure responsive warrants being in the title.

jcr:title: Multi-Column Control
jcr:description: ACS AEM Commons - Multi-Column control for inline, authorable, fluid column definition.

I almost thing it should be called "Ad-hoc Mutli-Column Control" .. but ad-hoc typically has bad connotations. 

WDYT?
