I'd like to be able to... 
- toggle columns on and offer
- filter the content (eg, show only the rows where the Size column is "Medium")
- re-arrange the columns into a different order
- resize the width of columns

Provides a easy way to filter a list with a simple client-side search feature (example add data-filter="true" attribute to the list). The framework will then append a search box above the list and add the behavior to filter out list items that don't contain the current search string as the user types.

We need a pager beyond the grid guys. Did I miss this one? Honestly Kendo Widgets would be good enough so we could build our own components for things like this.

Neither I nor anyone at my company can get it to work. We get a link in a email and the page fails to load at all. That means that I can't get a demo version of the project, I can't post in your forums, and I can't contact technical support. And you don't have a phone number on your site, so I can't contact you that way. If the only way of getting to you is via registration then you really need to make it work properly.

It would be a very cool thing to have a small WYSIWYG-Editor for mobile devices.
As far as I know, there isn't kind of this on the market at all.
So Kendo UI Mobile could be at pioneer-state

Create light-weight Diagram visualization control/wrapper.It may integrate with Telerik's Silverlight/WPF RadDiagram framework.

T4 Templates to slect in the asp.net Wizard to provide views controllers and and data connections to services

Currently if you append or insert to an object that uses a datasource (such as grid or treeview), none of the existing entires will have the template applied. This is a major problem and should be resolved ASAP.

It would be great to have a true Timeline control for showing events overtime on a scrollable axis.

Grids correctly display aggregate information in a groupFooterTemplate, but it only shows this information when the section of the group-by is visible (not collapsed).

Is there a way to display the aggregate information in a template that shows when that section is collapsed?

It would be great if it is possible to disable certain dates in the calendar. Maybe if it is possible to pass an entire array with calendar-date-objects, it would be more convenient to disable dates or highlight certain dates.
e.g. CalendarDateObject could have 3 properties:
- CSS class (this style would be applied to that certain date)
- Disabled true/false; default = true (if disabled, date is not clickable)
- Footer text (When you hover over the date, you can see this text in the footer)

By using an array of objects, you don't have to check if a date is in a certain array to change the CSS-class of that date. In the way it is now implemented, you have to write all lines of code to check if the date is in an array.

The forum is great but missing some critical features.

- Search a specific Topic area "Kendo UI Framework" or forum like "Data Source"
- Active Threads (show threads updated to today or since last visit)
- More notification options

It would be great if the chart control was able to produce a radar or spider chart, currently we have to use Silverlight to deliver this feature in our solutions. 

Add documentation for each significant versions. I should not need to always update to latest Kendo UI each time I need to fix or improve something on already shipped app. I know most things are backward compatible, but keep in mind that not every time we can afford the time to update it.

Please consider to add closed captions / subtitles to your existing webinars as well to each future recorded webinar; CC are a very handy aid not only for people that are hearing impaired but also for people like me for whom English is not their native language.

Thank you

Kendo UI for mobile, should provide a default look for NON mobile device. 

DataSource should be more feature rich. I consider following features a must in order to be able to develop complex UI's without the current pain

- Multimple models definition
- Associations between models
   - BelongsTo
   - HasMany
- Lazy load of associations!
- Allow use a REST approach for associations (send updates over a HasMany association to a service)
- Allow send the complete object

- Association validations
   - Unique
   - Exists
   - Min/Max number of elements

Have a setting causes only the most specific event handler to be fired/triggered.  This would be similar or identical to how a browser determines which value a property will receive when competing selectors are trying to assign it.  http://webdesign.about.com/od/advancedcss/a/aa062706.htm
