The lack of a horizontal scrollbar is noticeable :))

I am coming over as a Telerik Ajax developer. I am developing a pure html app against Amazon's S3 service and unfortuately the native sorting you provide is case sensitive. 

My sort ascending appears as

AAA
BBB
aaa
bbb

not very intuitive for end users...

handle RTL support in this awesome package. We really need such feature for using this library in our RTL-Language-Based Clients' projects.

http://www.requirejs.org/ might be a good fit.

Really important to have support for ARIA roles on these types of widgets. That's what they were made for, and jQueryUI does a pretty good job at this.

Accessibility is important.

It would be awesome if Kendo could be powered by Zepto instead of jQuery (optional of course) for mobile environments where we might not want to load all of jQuery.

Kendo + Zepto
It would be awesome if Kendo could be powered by Zepto instead of jQuery (optional of course) for mobile environments where we might not want to load all of jQuery.

For example, an anchor tag placed in a grid table cell is not currently rendered as HTML - instead it is displayed as text.

Good point - this will be discussed for the Kendo UI versions that are to come.

Menu widget has disabled items but lacks icons, separators and checked items

Buttons and toolbars (with icons and kendo themes) are much easier to use with Touch devices than the Menu widget

[Edited] Create a schedule view widget in Kendo UI Web.

Tooltips which can be attached to elements to provide additional information on hover.
Could either be taken from the title attribute, a string or a specified element.

Can provide additional styling and interactions going beyond the current restrictions of browsers title hover.

Enhance the window functionality with minimise and maximise buttons. 

Something similar to the following site (which also has some other useful functionality.)

Add extensions for templating engines such as JADE, HAML, or JQuery Templates, so Kendo UI can be built from VIEW files in MVC frameworks such as Express or Kanso on NodeJS.

Hello.
Congrats for this amazing framework to all webdev..
I was searching in the demo some features like forms (contact, validations fields, etc), but i cant see it.
is there some forms html5 based to start with kendo ui ?

thanks a lot!

Please provide first class Visual Studio IntelliSense support for easy development without the need of constantly looking up documentation or including "vsdoc" files like jQuery does.

Going through the demos I notice that if you drag some columns to the top to have the data grouped by that column and then click the X to remove the grouping the column headers do not line up with the column data. 

For example, when the autocomplete list appears or disappears, the entire page flickers to black for an instant. This happens roughly 50% of the time for me. I disabled all my extensions and that didn't help.
