It would be nice to have an ImageGallery component similar to the one available in UI for ASP.NET AJAX: https://demos.telerik.com/aspnet-ajax/image-gallery/examples/overview/defaultcs.aspx

It should have image add, remove, update capabilities. 

Enable the server-side rendering of the ListView widget. Similar to the implementation of the server row template of the grid:

https://demos.telerik.com/aspnet-mvc/grid/serverrowtemplate

This would help the pages containing the widget to be better indexed as the HTML content will be returned from the server rather than executing JavaScript logic to evaluate templates based on the data items of the widget.
