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.

Enhance the window functionality with minimise and maximise buttons. 

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

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.

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

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.

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.

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.

It's always selecting the first item when the filter is set to "contains"
Also, consider chaning the default filtering to "contains" like jQuery's AutoComplete UI control :) The others just don't work

I created this suggestion in the forum, but I thought I echo the same info here for others to enter their vote.

Recently, the Telerik ASP.Net Ajax released their Q2 with a nice & powerful "Notification" control. This control can be very useful with 3 tier apps using pure Ajax to notify actions that take place on the server or web service. I suggest to consider this control for future development.

Hello Team;
will there be a similar concept like ASP.Net "Master Page" which eliminate repeating part of a page in any new page? This would help designing a less crowded page.
Or a similar concept like Silverlight having a "Content" area that can be navigated to using AJAX. 

It would be nice to have built-in support for a row details feature in the Grid similar to the Telerik Silverlight GridView.  http://demos.telerik.com/silverlight/#GridView/RowDetails

I would rather have my users wait a couple of seconds for the page to load, than show all the components and have the browsers load the sprites and background images. i.e. the "flash of unstyled text" but only for images.

Is there any way you guys can forcibly pre-fetch all kendo images (maybe by creating invisible <img /> tags) so that the images would've been cached, and the UI appears instantly, even for people through slow connections

maybe, you can make this optional - because it will be useful for people using a lot of kendo elements on the page - when compared to the people using it as a minor portion.

I would love to do:
kendo.preload(function()
{});

The seems to be some general usability issues with some aspect of most of the controls when used on the iPad. For instance the combo box shows the drop down twice on focus and then shows the keyboard, which then does not hide again.

You cannot scroll the grid it scrolls the page, little things like this make what could be fantastic a bit frustrating.

Make it easier to change the themes without having to recode all our CSS code. Many of us have already invested a lot of time in custom JQuery UI ThemeRoller themes for our applications. If we had a conversion tool that saved us from all the CSS recoding I would gladly drop UI and switch to Kendo ASAP. 

Add better namespace support 
in the form of an include or using statement file for 
ease of code resuse. (Key word there is Ease) 

import Kendo.UI.widget;
import Kendo.UI.validation;
import MyAwesomeClass.THX.Teleric.ILUVU.BYEBYE;


I'd sing your good deeds across the land if you did that.

I think there is a real need to try and get the ui feeling much more like a desktop app with regards to how data is added to a grid - I have always found the Telerik Ajax grid to be overly cumbersome for entering new rows of data. There needs to be a fluent approach to this  where by tabbing through all of the columns in the last row in the grid it should add a new row that can quickly be updated again via tabbing - much like win form controls; the aim should be speed and ease of use.

It would be nice if Kendo offered an online tool that could produce a custom, minified JavaScript download with only the JavaScript code for specifically selected features.

In addition to Line and Bar chart types, it would be nice to have support for the Pie chart type.

I would like to request, for the following controls: Rich Editor, Data Filter, Masked Input for building business apps.
