Instead of pages like this, which exist for every control and aren't very helpful:
http://www.telerik.com/help/aspnet-ajax/scheduler-appearance-skins.html

I think the skins page should actually render the control and allow developers/designers to select a skin from a drop down to properly demonstrate how the control appears in that skin. 

The logic behind this is somewhat similar to the property explorer pages. As with the property explorer pages, the RenderMode should also be selectable from the proposed skin page because it affects the way the skin is rendered. 

Without this feature I find myself starting a test page, typing in a skin name, save changes, load page, new skin name... repeat, repeat. Please add this feature to make this process a whole lot easier.

IMPROVE: RadCalendar and RadDatePicker to be localizable using GlobalResources

FIX: $create of controls with same parent are created in reverse order if using RadAjax

Since Responsive Design is the actual trend, and most of the free frameworks have compatibility issues with Telerik Controls due to the Global Styles, I suggest a new Responsive Framework. A Telerik Responsive Framework, that out of the box would work perfectly with all the Telerik suite. I believe that this would be very appreciated by all your customers. Some of the controls should also be prepared to work with this framework resizing it's elements according to the device.
