This week I've been mostly...
* hacking to get real DOM support in the core. This idea was however rejected by the others. The end result is to provide a "children" property to all container elements. This I'll probably do next week.
* implementing proper i18n support and writing a howto in the wiki.
* planning the style support. This is something I'll start implementing next week.

This week I was also contacted by Ashwin, a biochemist from India. He was also working on a GUI for gD. We've been hacking together on it now and it looks very promising.
