Lots of forums use bbcode and adding support for this to the Editor would be great.

In the editor, the image manager search should search the current folder and any folders underneath it and return all matching images. Currently it only searches the current directory.

Format Painter is a tool on the ASP.NET Ajax version of the editor - I would really like to see this ported to the Kendo  UI and MVC versions of the same control.

Add auto height option to Editor, that's expands editor by entered context. (I's available in inline mode, but very need in iframe)

Allow us to activate the inline editor by double-click or by an event.  This way users can click inside the HTML, select it, copy,etc and if they actually want to edit they can double-click or click a button.

Such that it looks like:
a) jdkfjdk fdkfj dkjf dfkjdf kjf
b) djfkdjfk df dkf dkfjdkfjdkf dkfjd
c) kdj fkdjfk djfkjd fkj fkfj

Word does this and it is useful. Uppercase and Lowercase options would be useful too.

Currently when inside a table, the functionality for adding more tables disappears and is replaced by the table edit tools, however in our software tables are used to layout the HTML rendered by the editor, which prevents users adding tables at all. We need to keep ours set up this way and cannot switch to a CSS way of building the HTML :(

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.

Posting suggestion based on forum topic: http://www.telerik.com/forums/placeholder-html-attribute

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.
