This may just be a misunderstanding of the functionality. 
Nicely understated!
The styling paragraphs in the support documentation (via webassist.com support pages) begins:
"In the newest version of HTML Editor, the Styling tab has been enhanced to provide a much greater set of options for applying CSS style sheets to your HTML Editor instance"I have never (personally) had a problem with adding the site styles to the Editor Interface, so that the input area appears to the client as it would on the final page.
The writers of this could have more accurately written:
"While some of the more useful functionality has been removed from this edition, we have added the capability of adding individual styles - style by style, property by property, in order to compensate for the removal of the ability to import styles directly from your site stylesheet"Could you not have gone the whole hog and added the 'enhanced' bits as well as keeping (and further enhancing) the usefulness of the previous verion?
