Can you please explain what you mean.
Termin wrote:a separate plug-in to reduce css
A CSS minifier would be nice. However, recently I investigated a bit on this issue, and
found that minifying the CSS will only bring moderate improvements compared to minifying (or avoiding) JavaScript. And most likely it is more important to add compression (can be done by configuring the server accordingly) to CSS and JS.

AFAIK there are no editors which widely support the new HTML5 elements (e.g. <figure>), yet. I hope that will improve in the future.
