CBEnhancer has the ability to provide code from the clipboard as formatted HTML. To paste this in LiveWriter you normally have to choose "Paste Content" and then select HTML. With this plugin it's just one mouse click to do the job. If normal text is in the clipboard it will act like the default paste - if HTML formatted content is there it works like "Paste Content / HTML". I also use this without CBEnhancer - it's simply faster than "Paste Content". I didn't find a way to assign a hotkey to a plugin - else I would say it's perfect.
