The UI for ASP.NET AJAX is a really mature product (perhaps the most mature product line we have), and consists of over 100 controls. At this point there are very few features we need to add, because demand for them is low. Most of our clients use the suite in existing applications and the current feature set is usually enough.
This does not mean that the product is coming to an end. There is a myriad of applications built with it out there, and we intend to keep going and to provide support to our clients.
If you do have any feature requests, you can add them to our feedback portal so management can gauge the public interest and impact of their implementation: https://feedback.telerik.com/project/108.
