• it is a highly specialised Web Site Editor – not a general editor
• it integrates with your tools (BBEdit, Style Master, CSSEdit)
  -- a humble, yet brilliant feature,
• it creates sites not (just) pages, with folders for includes,
  media, scripts etc, and it remembers them afterwards
• it helps thick heads put thing in order, both the site, the code,
  the css, your images -- with a built-in image center/database
• especially: it uses your CSS file as a resource when you work
  with the HTML code
• but ... SEEdit is just a tool (and not immune against dishonest
  reviews) --, valid code is your own responsability, though SEEdit
  helps you stay valid!
• it includes a previewer -- and it is the closest a text editor
  comes a WYSIWYG editor
• and there is more ...!
  
  

The language/unicode support is not complete yet, but the responsive developer
is working on it!

Try it, and get into it. You will be suprised how interesting and well thought out
the approach is.
