I've been busy with libcroco since my last diary. The CSSOM implementation is going forward. The parser can already parse trivial stylesheets at a SAC level and build a stylesheet abstract tree at the CSSOM level. Still my implementation of CSSOM doesn't support @media and @import rules yet.
I should find the time to dive again into the MlView edition code a bit. This css2 support stuff just sucks all my time <grin/>
