It seems Kendo UI mobile already covers Android and iOS.  Are there plans to incorporate Windows 8 into the roadmap?  It would be very appealing to developers if there is one framework that can be used across all platforms.  

a grid with an editable column will show if there is no data in datasource. 

Telerik has a graphical timepicker control that we're using on desktop applications (WinForms). We'd like something similar for web-apps deployed to our intranet/extranet. The essential features for us are the AM|PM toggle; the display of the 12 hours in several columns and the ability of the developer to define/limit the minutes interval (e.g. 15, 30, 45, 00) in the bottom pane. We are using 15-minute intervals and so the current Kendo dropdown-list timepicker would have to contain 96 items. The Telerik visual approach avoids a long scrolling list:

Add similar functionality as AngularJS has:

sparklines are important data visualization that is missing. would be great to have it. you can take inspiration from http://omnipotent.net/jquery.sparkline/#s-about

Smart Input.  iOs in facetime has an input that has onBlurEmpty, onBlureChange , onFocus events.  It also manages the style of the state.  It has a bound clear input button that send the caret to the beginning, while showing the preset value . It also has a preset value that is in a different style.

With this widget you can make passive calls to the database for CRUD stuff.  

Look at the contact section in FaceTime.

Add ability to insert SVG html into Kendo Chart areas like the title. Example would be ability to add my own TSPAN to the title to help style it more.

Another important thing for upload element is file list template. Somethink like 

<script id="template" type="text/x-kendo-template">
     <div>#= filename #, [#= filesize#]  
          <span class="menu">
          <ul>
               <li>#= button_delete #</li>
               <li><input class="k-button" value="Insert into text" onclick="insert()"></li>
               <li><input class="k-button" value="Copy path to bufer" onclick="copy()"></li>
          </ul>
          </span>
     </div>
</script>

This way i can path either tmplate ID or template object and affect list of files. 

Because upload is a very important thing nowadays and usually require more options than just upload.

For example. I have article and I attached 3 files to it. Now i open article for edit because I want to add 2 more files but delete one. Of course i could make separate list of already uploaded files. But better would be to give to this UI element list of files to be populated on initialization.

Adobe AIR imposes some security restrictions on Javascript code written in certain ways/styles (e.g., use of "eval" and "Function" declaration inside code, which are used in KendoUI), but offers a fairly complex implementation facility (called the "sandbox bridge") so developers can work around these security restrictions... Please provide Adobe AIR/Javascript developers "BEST PRACTICES" articles/tutorials on how to code the KendoUI widgets that are incompatible with the Adobe AIR security restrictions.

There is no way to use tree as a column in a grid.
A TreeGrid would use hierarchical datasource where one column would show nodes and other columns would show node properties.

Here is an example (from Sencha Ext JS)
http://dev.sencha.com/deploy/ext-4.1.0-gpl/examples/tree/treegrid.html

On this page: http://demos.kendoui.com/web/grid/column-menu.html
See the "Shipxxx" column.
IE can input contents and submit but the menu seems shake.
Other modern browsers can NOT input contents but the menu Not shake.
Please fix both! Thanks~

Is there any way to implement checkbox list using kendo web?

and a grids toolbar with the commands and template at the same time throw a search input text that filters the grid. 

Won't hurt to have one, to have a KendoUI version would be pretty in the eyes. 

See http://www.highcharts.com/demo/line-basic for a good example of  Client-side Chart Export

When the destroy operation fails for some reason (exception or ModelState error) the item on the client will be removed.
Don't remove the item from the grid if operation fails in the backend.
 

I created a custom theme using the theme builder. I then created a grid (using the MVC wrappers) and included a column menu. When I drop down the column menu there are no sprites drawn for sort, filter etc - there are in the provided Telerik themes. These images should also be included with custom themes.

I've been trying to use these great UI widgets in PHP update forms and the lack of documentation on how to use the datasource and widgets together in PHP forms is incredibly frustrating. Seems like it would be a very small job for one of the kendo gurus to come up with the following and add it to the examples and/or documentation:

Update forms:
In update forms you need to initialize the widget(dropdowns, comboboxes, etc...) with the value of the column in the database and provide the list of options to choose from to edit the data. I assume there is a way to do this using the datasource but there is zero documentation on this. Please provide a simple example with a standard php update form with the widgets pulling the form data from a simple query based on a selected id, just like every standard php form on the web, with clear code showing us how to configure the widgets so that they contain the data from the db when initialized and providing the list of options via the widgets dedicated datasource.

This is very simple stuff and should take one of your junior techs 10 minutes and would make some of us very happy.

Thanks!

Add TickDistance, AutoRange and Step to the line Chart like the Telerik RadChart.  When querying a web service and charting a dynamic/variable number of values, the current chart results in grid lines too close together and overlapping x-axis values.  This would space the grid lines and labels based on the number of values and available space.  This is from the RadChart documentation:

The TickDistance has to be used together with AutoRange. When AutoRange is set to True, the axis Step value is calculated depending on the data range, the available space and the TicksDistance value. Since TickDistance defines the minimal distance between two ticks, increasing its value will cause the Step value to be increased too.
