Security - We will get there

I came across OpenWebSuite as I was searching for a tool to develope theme for drupal. It can help you create both html and css files with some sort of generator/code insertion/snippet etc. And it can do tag auto-completion as well.

It's still in the early development but worth to have a look. When combined with Firebug, I should be able to get my themes done much easier.

Other tools like TurboCSS, Personal web editor etc I came accross are either too premature or just don't serve my purpose.
