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.

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.

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()
{});

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

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. 

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.

Make it easy to add Kendo UI to ASP.NET projects and provide a NuGet package.

Sure the IE Mobile browser is not fantastic (even the Mango version feels like it has issues), but will you be supporting the WP platform?  That would round out all the worth while mobile devices in my opinion.

Web devs have a million different frameworks out there.  Talk about how this differs (or is a companion) from using jQuery UI (looks like it competes), Knockout, extJS, etc...

It would be great if you could zoom in on the charts like highcharts,
http://www.highcharts.com/demo/line-time-series

A lot of the charting functionality there would be great.

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

[Edited to remove tools already included in beta.]

To make it easier to add Kendo UI to a project, create a Ruby Gem package.

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

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.
