I've noticed that Date, Slider and Sortable use the jQuery UI Plugins. That would be better if the documentation uses the same convention for all of them, or at least mention the Slider is actually the jQuery UI Slider:

Eq. jQueryUI Datepicker for AngularJS / Slider based on jQuery slider / AngularJS bindings for jQuery UI Sortable

Suggestions:
jQuery UI Datepicker for AngularJS
Slider based on jQuery UI Slider
AngularJS bindings for jQuery UI Sortable
