Such functionality would improve the user experience for UI interaction of the end-users with the RadEditor tools.

Such behavior can be achieved using the following customization with the RadEditor control:

<telerik:RadEditor ID="RadEditor1" runat="server" OnClientLoad="OnClientLoad">
</telerik:RadEditor>
<script>
    function OnClientLoad(editor, args) {
        editor.attachEventHandler("onkeyup", function (e) {
            if (e.keyCode == 27)
            {
                closeContextMenus(editor.get_toolAdapter()._contextMenus);
            }
        })
    }

    function closeContextMenus(contextMenus) {
        for (var menu in contextMenus) {
            contextMenus[menu].hide();
        }
    }
</script>

Elapsed time, Estimated time and Speed are not calculated correctly. 

I don't know what you call this button but it is a crossover between a drop down list/mega menu and a button.

Very simple example:
Google's "More" button across the top next to News/Videos/Maps and then there is the "More" button with the other options. 
https://www.google.com/#q=dog

Next example:
Your site! The skin selecting drop down:
http://demos.telerik.com/aspnet-ajax/grid/examples/overview/defaultcs.aspx

The option for a full fluid width like this would be nice along with the possibility of a fixed or fitted width. I also really like the animated arrow up/down.

But the mega menu example is Amazon:
http://www.amazon.com/

Their buttons/drop downs in the top right for "Your Account", "Try Prime", "Cart", and "Wish List".

These are beautiful and would be great functionality. It would also be ideal if the button/link itself that triggers the drop down doesn't have styles like the skins so they can easily be integrated into a website's existing navigational items and site design.

At present, when a Telerik product is installed via an automated installer (WebInstaller or a downloaded MSI package), a shortcut to it is added on the desktop.

This feature should be optional, e.g., via a checkbox during the installation wizard.

Here is the missing resource name: pTelerik.Web.UI.Skins|Telerik.Web.UI.Skins.Web20.Common.radGradientListSprite.png
You can see if this is your case as well by decrypting the WebResource request that fails as shown here: http://blogs.telerik.com/aspnet-ajax/posts/07-03-27/debugging-asp-net-2-0-web-resources-decrypting-the-url-and-getting-the-resource-name.aspx

Please create high contrast theme for people with disabilities.

The best colors are yellow and black and there should be two combinations: yellow on black and black on yellow.

Please look at attachements for very good example.

Hi,
It would be so usefull a template or tool like codesmith or ironspeed to generate database-driven applications or at least a set of pages for CRUD operations where I can list the registers of each table/entity and edit it contents and Its relatives.

Thanks
Ángel.

When adding a link with a class name, the Unlink command cannot remove the formatting. 

Temporary solution is to clear anchor's classes programmatically via the ApplyClass command:

<telerik:RadEditor runat="server" ID="RadEditor1" OnClientCommandExecuting="OnClientCommandExecuting">
    <Content>
        <a href="http://www.telerik.com" class="my-class">link</a>
    </Content>
</telerik:RadEditor>

<script type="text/javascript">
    function OnClientCommandExecuting(sender, args) {
        var command = args.get_commandName && args.get_commandName();

        if (command === "Unlink") {
            var myArgs = new Telerik.Web.UI.EditorCommandEventArgs("ApplyClass", null, "");
            sender.fire("ApplyClass", myArgs);
        }
    }
</script>

The text in the tabs' titles of the Sliding panes of the Splitter control are not properly rotated.

There are several other suggestions along these lines, but in general, Telerik needs to make their data input controls more consistent in the implementation of a "Label" property. Without such consistencies, it makes including controls that have this property and those that don't together on the same page much more difficult. As of the writing of this, the DropDownList and DatePicker controls do not have a Label property. There is no apparent reason why this should be so.

All of the input controls should have this property.

It would be helpful , if you provide image library like Visual Studio provides.
The image library can have all the standard and specific icons of telerik.

Possibly as an extension of the Media Player... a Web Cam recorder.
