Telerik r.a.d.editor MCMS Edition V2
I have been testing this for the past week - Its very cool.
But - I don't know if it will get wide adoption in large MCMS implementations with > 5000 resources as the resource gallery explorer loads all galleries & resources ; therefore taking ages to load and often timing out (even on MASSIVE servers) - aparently a fix is on its way ;
but that didn't stop me rolling back to the out of the box MCMS editor at a client's site.

Telerik have announce the availability of v2.0 of
r.a.d.editor MCMS Edition. The new v 2.0 is available at no cost to
MCMS customers and you can download a copy from "My Licenses" in your Client.net account. The new release has a number of improvements to improve the experience of
MCMS end-users.
What's new in v 2.0:
Features:
- The LocalImage appears or not depending on the value of the MustUseResourceGallery property of the placeholder definition.
- Improved file browser dialogs (Image, Flash, Media, Document) with Windows-like look and feel
- Improved look of the editor, easier to change the visual look of the editor by editing the schemes' CSS files
- Added UseClassicDialogs property that makes the editor's dialogs appear either within custom, fully CSS-configurable "windows", or in the default IE dialogs. (Default is false, that is the editor uses the custom dialog windows).
- Cleaner HTML output and better application of CSS styles
- Indentation of HTML in code view.
- Updated to work with Internet Explorer with Windows XP Service Pack 2.
- Improved clientside performance.
Bugs Fixed:
- Fixed a bug which occurred when attaching an eventhandler to the SavingContent event. In the event handler the old (original) content of the editor would be returned, rather than the new value.
- Fixed a problem with the *.* setting for document filters.
- A number of smaller bugs fixed mostly related to the quality of the html and the editing process, enhancing the user experience.
