title: A good HTML5/CSS3 editor
body: <p><br>
  I recently switched from Aptana Studio 2 to Aptana Studio 3 (both as an Eclipse [Helios] plugin), with the hope that the new version will bring HTML5/CSS3 support, but so far, the support was partial at best (no docs/auto-complete).<br>
  So I'm now looking for a good web-editor with a good support for HTML5/CSS3,<br>
  Anyone have any suggestions?<br>
  PS: zen coding support will be greatly appreciated.
  PS2: also suggestions about full web development IDEs (which include support for PHP5,CSS3,HTML5,zen coding and Javascript) will be more than appreciated.</p>
  
  <p>Thanks in advance,
  GZ </p>
