Improve the click responsiveness for modals

Opening an ionic modal with “$ionicModal.fromTemplateUrl” is much slower when opened for the first time than opened for subsequent times.

A potential workaround to speed up the first time opening is to preload the modal in the calling controller, e.g.

    function preloadModal(templateUrl) {
        $ionicModal.fromTemplateUrl(templateUrl).then(function (modal) {
            console.log('IonicModalService: Preloaded template: ' + templateUrl);

This works. However, this does not seem to be the best way to do it, therefore, does anyone know any better way to accomplish this?
