How configure number of max fields to user add.

I develop a hacker

 document.addEventListener('fieldAdded', 
					 function(e,data,dat1) { 
				 

				 $scope.addFields++;
				 	$timeout(function() { 
				 		if($scope.addFields > $scope.maxFields){
				 			$scope.formBuilder.actions.removeLastField(); 
				 		}
				 	}, 100);
				 
}); 

A.prototype.removeLastField = function() {
                  var t = !1,
                      e = this,
                      r = this.d.stage,
                      o = r.getElementsByClassName("form-field");
                  
                  var lastId = e.data.lastID;
                  var lastIdNumberSplit =  e.data.lastID.split('-');
                  var lastIdNumber = lastIdNumberSplit[lastIdNumberSplit.length-1];
                  
                  var realLastId = "";
                  
                  for(i=0; i < lastIdNumberSplit.length; i++){
                  	
                  	if(i == lastIdNumberSplit.length-1){
                  		realLastId += parseInt(lastIdNumber) -1;
                  		break;
                  	}
                  	
                  	realLastId +=lastIdNumberSplit[i];
                  	realLastId += '-';
                  	
                  	
                  }
                  
                  
                  var i = document.getElementById(realLastId),
                  s = $(i);
              return i ? (s.slideUp(250, function() {
                  if (s.removeClass("deleting"), s.remove(), t = !0, e.save(), !r.childNodes.length) {
                      var A = r.parentElement;
                      A.classList.add("empty"), A.dataset.content = f.default.current.getStarted
                  }
              	}), document.dispatchEvent(u.default.fieldRemoved), t) : (console.warn("Field not found"), !1)
              },

Not a feature but should be. Glad you found a solution.
