Code before:

                $scope.completion[device][folder] = data;

            }).error($scope.emitHTTPError);
        }

Review comment (refactor):
Sorry, I didn't mean you should remove this.  It's needed to eject old entries from the `idToRemoteGUI` object.  Same with the loop below.

Code after:
                    $scope.completion[device] = {};
                }
                $scope.completion[device][folder] = data;
                recalcCompletion(device);
            }).error($scope.emitHTTPError);
        }

        function refreshConnectionStats() {
            $http.get(urlbase + '/system/connections').success(function (data) {
                var now = Date.now(),
                    td = (now - prevDate) / 1000,
                    id;

                prevDate = now;

                try {
                    data.total.inbps = Math.max(0, (data.total.inBytesTotal - $scope.connectionsTotal.inBytesTotal) / td);
                    data.total.outbps = Math.max(0, (data.total.outBytesTotal - $scope.connectionsTotal.outBytesTotal) / td);
                } catch (e) {
                    data.total.inbps = 0;
                    data.total.outbps = 0;
                }
                $scope.connectionsTotal = data.total;

                data = data.connections;
                for (id in data) {
                    if (!data.hasOwnProperty(id)) {
                        continue;
                    }
                    try {
                        data[id].inbps = Math.max(0, (data[id].inBytesTotal - $scope.connections[id].inBytesTotal) / td);
                        data[id].outbps = Math.max(0, (data[id].outBytesTotal - $scope.connections[id].outBytesTotal) / td);
                    } catch (e) {
                        data[id].inbps = 0;
                        data[id].outbps = 0;
                    }
                }
                $scope.connections = data;
                console.log("refreshConnections", data);

                refreshRemoteGUI(data);
            }).error($scope.emitHTTPError);
        }

        function refreshRemoteGUI(connections) {
            if (!$scope.showRemoteGUI) {
                $scope.idToRemoteGUI = {}
                return
            }
            var newCache = {};
