Does the subject deserve this pane?
function (subject) {
    var ns = UI.ns
    var kb = UI.store
    var t = kb.findTypeURIs(subject)
    if (t[ns.rdfs('Class').uri]) return 'creation forms'
    // if (t[ns.rdf('Property').uri]) return "user interface";
    if (t[ns.ui('Form').uri]) return 'edit form'

    return null // No under other circumstances (while testing at least!)
  }
