It would be good if you could enable the KendoUI for MVC buttons to have an "image + text" look and feel in the same way that the Telerik MVC Extensions did.

Thanks 

When setting the value for the rich text editor, if the object value is null, it blows up. I have to check if the value is null and if so, set it to an empty string. 
var propValue = linkData[propertyName];
                        var editor = $(this).data("kendoEditor");
                        if (propValue) {
                            editor.value(propValue);
                        } else {
                            // clear value
                            editor.value( '' );
                        }

The validation can contain fatal errors ( form submit is not allowed ) and warnings ( form submit allowed ).

For example blank/short password is a warning, beacuse it allowed but not unadvisable.

add the ability to choose the weekly in datepicker

When minimising windows put them in a row at the bottom left of the screen also allow windows to be created in Javascript (see wijmo). 

The possibility to have both edit modes in a grid. I want to (for example) instant edit my columns in the grid, but also have a (custom) popup window wich will allow me to edit more fields not included in the grid (but still in the datasource ofcourse).

Its a small thing, but annoying.

i dynamically add subitems to the tree on expansion.
therefore i do not need to load the whole data on start.

so, on the tree init i just have on the items, that contain children an <ul></ul> to indicate it has children.
that works just as expected.
but when the user clicks on the expand icon, the event treeView.expand does not get fired.

My current workaround is, to add an invisible dummy
<ul><li style="visibility:hidden"></li></ul> to indicate there are subitems.
and when the expand event runs, loading the item, and removing the dummy... 
Thats far from perfect.

It would be nice to be able to adjust the values of min, max and step after widget initialization. 

You refer to Kendo UI Premium Forums in your FAQ and web site, but post no link to this so I cannot find it! I am a paid up customer and want proper support like other Telerik products.;

if you compare the rad editor with the Kendo wysiwyg editor, the Kendo one lacks the wide range of functionality. It would be nice if they were the same.

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

Position the grid's sorting icon on the left side of the column header so that it is always visible even when the column header's label is wider than the columns width. This will also eliminate the icon overlap of a narrow column that is sorted and also has the "columnMenu" option set to "true"

Within a short look at Kendo I did not find out whether you support animation for navigating the web UI like it is possible in silverlight or Kendo UI mobile. 
Example: after selecting an item in a list a window from the right side turns in showing some details to the selected row.

Do you / will support similar features?

KendoUI would seriously benefit from some killer apps and more marketing in general. A showcase gallery would be a great place to start. 

Currently complex elements (Like the Grid and the Chart) have so many properties and methods that the page has so many DOM elements it takes forever to load.

I want to resize the splitter height but only when resize has stopped.

when adding an additional tab to a tabstrip - the tabbing behavior does not work as it should when switching tabs

use the html below:
then select in the browser the dynamic tab - works ok
then select in the browser the static tab - this results in both tabs being displayed

HTML to reproduce:
<!DOCTYPE html>
<html>
<head>
    <title></title>
    <link href="styles/kendo.common.min.css" rel="stylesheet" />
    <link href="styles/kendo.default.min.css" rel="stylesheet" />
    <script src="js/jquery.min.js"></script>
    <script src="js/kendo.all.min.js"></script>
            <script>
                $(document).ready(function() {
                    $("#tabstrip").kendoTabStrip({
                        animation:  {
                            open: {
                                effects: "fadeIn"
                            }
                        }
                    });
					
					var tabstrip = $("#tabstrip").kendoTabStrip().data("kendoTabStrip");
					tabstrip.append({ text: 'Dynamic Tab', content: 'Dynamic Content' });
					
 					//var firsttab = tabstrip.select();
					//tabstrip.select(firsttab.next());
					//tabstrip.select(firsttab);
                });
            </script>
</head>

                        <li class="k-state-active">
                            Static Tab
                        </li>
                    </ul>
                    <div>
                        Static content
