I was using save and edit buttons in RadEditor on ASP.NET Ajax extensivelly. Now, I've moved to MVC and noticed that these buttons don't exist at all!!! It's very weird. Ok, save functionality can be achieved fairly easily, but printing the content of an editor not much.
I assumed that, when you were building MVC controls you would deliver the same functionality as in Ajax controls. 
Anyway, adding these buttons to editor tools would be great.

If you provide any editor control which render both OpnXml data as well as Html data, that will more helpfull for us.
OR
any convert method in kendo UI editor which convert OpenXml to Html and vise versa.

Add a configuration option to the editor to allow the TAB key to indent the first line of a paragraph (add whitespace) rather than tabbing between elements.

When the cursor is inside a table cell, typing the TAB key should move the cursor to the next table cell (moving left to right, top to bottom).

I would like the editor to have more support for Bootstrap editing. Adding and controlling col-* div containers using the editor. Most modern editors have such control but none excels. Adding support for glyph icons and responisve tables and commonly used class for them, such as "table-striped".

ASP.NET AJAX RadEditor is  much user friendly (i.e. image resize with mouse, styling some simple properties like margin...etc.). We use Kendo UI and HTML5 in our new projects, but in our custom CMS we had to integrate RadEditor, because it is very smart and user friendly and gives  a great helping hand and many functionalities to our users who has no html and css experiences.

Kendo Editor is still not a tool for a CMS, it is good only for writing some sentences to news or for some very-very simple editing task.

Editor does not support placeholder. It would be nice, to have this feature.

KendoUI Editor support import and exporting files to and from DOCX format

It would be nice if we had a Table Wizard (as in RAD Editor) for changing formatting for tables inside Kendo UI Editor (e.g. changing style and color of borders, font and background colors for cells, merging and splitting cells, setting size of the table, and other features that exist in RAD Editor). We're migrating to Kendo UI from RAD controls and Table Wizard for Kendo UI Editor is needed.

Are you planning to implement something like Table Wizard in the near future?

It would be nice to have a boolean property with the Editor to detect an enter keypress, and end the current style.  We have custom css classes that the user "can't get out of" without going into the html view.  Another option would be a tool that would "end formatting" so that further content would be unformatted.

This problem can be seen at one of the demos, http://demos.telerik.com/kendo-ui/web/editor/styles.html.  Go to the end of the content, type something, choose the "highlight" style, hit enter.  The style is permanent until you use the arrow key down or click below the current content.

It would be helpful to have backend server support for node.js (express) for the  image manager API.   Perhaps it could be started in Kendo Labs as a joint community effort.  
Also,  the API needs to be tuned to support the everlive URI hooks.  While not go ahead and create and image content type with the API on the everlive side that talks to the editor image API.

We build a project on Kendo, and incorrectly assumed we would see similar levels of tools in the ditor as per the ASP.Net ajax implementation. We were surprised to find the image editor was not available. I guess I dont really understand why you couldnt call the existing functionality from the server side using Ajax as a fast way to beef up the functionality for Kendo?

Currently the floating toolbar for an inline Editor (a contentEditable div as opposed to a textarea) is positioned relative to the document body, not the Editor itself. If for example your Editor is in a div with its own overflow-y: scroll while the body has overflow: hidden, as is the default in a SharePoint 2010 page, then as you scroll this div, your editor will scroll in the div, but the toolbar remains fixed, when it should scroll along with the editor. We need to be able to append the toolbar to an arbitrary container so that it can be positioned relative to the editor.

I'm looking for a way to use the Kendo UI inline editor with H1/H2 tags and not only DIV tags. This is currently not working when adding contentEditable: http://www.kendoui.com/forums.aspx/kendo-ui-web/editor/use-in-place-editor-for-headlines-h1-h2.aspx

Add the possibility to stop a user from deleting an image/folder in the ImageBrowser connected to the Editor. As it is now you can stop it serverside, but there is no way to prevent the folder/file to from being removed on the client.

Create events for the ImageBrowser for both standard widget and MVC Wrappers.

Many times I want to style my images that are being inserted by wrapping them in some custom HTML DIV's and SPAN's.  This would allow them to include code for prettyPhoto for example, contain classes that can float the image right or left, allow for margin's, etc.

Including the capability of adding snippets that would wrap around the image when Insert is clicked would add a lot of value.

I guess templates could be used, but the capability would need to be there.

Anything to allow me to modify the way the Image HTML is inserted into my text would save me lots of time.

It would be nice if the placeholder text for the Editor widget were removed on element focus.

The editor should be able to paste text from word 1:1. Currently it's not working wekk,
