Q:

Custom sliders in Shiny

I'm really frustrated by the limited sliders shiny currently provides. I would like to have a slider that:

Has both an inputvalue and a slidervalue that correspond, like the sliders from angularjs: bottom of this link and here
Doesn't refresh the entire every millisecond I try to find to right value. I want it to be reactive, but not 25 times when I'm looking for the right value.

Any help is much appreciated.
Edit:
Managed to get the AngularJS slider working after the hint below and quite some tries. Please find the repo here. I although don't manage to get the data back into R. You should do that with the Shiny.onInputChange function. I tried it like this:
        <script language='JavaScript'>          
            var app = angular.module('rzSliderDemo', ['rzModule', 'ui.bootstrap']);
            Shiny.onInputChange("Robject", app);
        app.controller('MainCtrl', function ($scope, $rootScope, $timeout, $modal) {
        //Minimal slider config
        $scope.minSlider = {
        value: 10
    };

});
        </script>

and of course played with the app object name but the slider just keeps failing.

The guys from dreamR have released a package that solves many of the missing widgets:
