Finally!

I have been looking for something like this for ages! It astonishes me how few people realise the need is for clean code not visual embellishment.

Could I suggest a font size increase button for the display of the text. i.e one that allows you to select from options in the CSS of WYMeditor.

Of course the ultimate would be the ability to tag text with XML tags from a nominated Relax NG schema but lets crawl first.

Hmm, I think it will confuse the end-user (if I understand well what you say).
In Firefox, Ctrl++ increases the font size...

Yes, I'd like to do something like that, maybe in next version (0.3), using jQuery.
