I would really like a ProgressBar control. The reason why I want a progressbar control in kendo ui is so that the look and feel of my application is consistent throughout.

I would suggest to enter the function menu script that is described in the following link. This is an interesting application that really makes it easy to navigate the menus user an.

Is integration with aerelia planned?

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.

Integrate with breeze.js (www.breezejs.com/). Kendo UI needs better change tracking capabilities and unit of work support and automatic fix-up of navigation properties. Kendo UI's DataSource only deals with entities of a single type. Kendo UI's ObservableObject tracks whether an object is new or dirty, but not whether an object is deleted or detached. On removing items from Kendo UI's ObservableArray, items are not marked as deleted. Etc.. Breeze.js' entity manager deals with entities of all types, tracking their changes, fixing up their navigation properties, and submitting their changes in a single unit of work.

When we do some pages just like register, we need step by step, a smart wizard plugin will be useful.

This is a great framework that takes the best ideas of angular and react without being as difficult to learn as either of them.  Please consider it.

This would be great. It is kind of what I had in mind when I suggested this: http://kendo.uservoice.com/forums/127393-kendo-ui-feedback/suggestions/2662536-add-grid-column-filters. I currently use this type of filter where the filter is just a free text field and upon blur or enter, it runs the filter. having control over the type of filter syntax used would be great ... so that it is Linq, List, Oql, or custom string compatible. This is a common feature in the Telerik Grid when used in client mode...

For example; similar to http://www.highcharts.com/stock/demo/arearange

Having area 'scatter' support, such as 'scatterArea', and 'scatterAreaRange', like the existing 'scatterLine', is also desirable.

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?

Since now Google started doing it on Gmail, I believe that we'll need even more these features.

Excel export with image for grid

It would be a great help if there was a way to add a Trendline to a line chart in the DataViz collection.  This function is available in excel and other similar programs.  
The wiki page explains:

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

AngularJS, which just released 1.0, is gaining a lot of fans (including myself and my developer-friends). There already is an AngularJS adapter for jQueryMobile, and I hope the KendoUI Team will work on an AngularJS adapter for KendoUI very very soon. I think a solid AngularJS adapter implementation will pull my team over to KendoUI for good.

If it is at all possible, please implement drag & drop inside the grid to enable users who need to manually sort items in order of importance (for instance a list of books I they wish to show in certain order).

Maybe CSS3 can do more nice text,textarea,button, but in IE7&8, can not support border-radius,box-shadow,text-shadow, so we must use picture to do this. I want to all the form element seems the same in KendoUI support browsers.
Just like: Uniform,Niceforms,Jquery FormOne,jqTransform,jNice and so on...

Can we make the tabstrip scroll-able instead of wrapping tab items to another line? Let's say I'd like to target both Ipad and iphone and the tabstrip would have 6-7 items.

Although Kendo has fency filters with different operators (StartsWith, Contains) on different columns based on data type, Most business users  like to have excel AutoFilter(Multi select checkbox) where they can choose what companies, countries they want to see

You can see a live demo here at - select company, country or any other column.
