this is a great idea.
One minor issue: in an Firefox 3.6.10 under OS X 10.6.4 the your context menu item (the entry "copy as HTML link" is not inline with the other commands but has serveral whitespaces prefixing it. Do others have the same problem? Could it get fixed?
And as a feature request: how about to make it possible to add a custom inline stylesheet to the resulting HTML-code that would automatically make this text look different, when pasted somewhere else?
Thank you for this extension anyway!!
