There have also been some debate about AbiWord UI and its customizability. Martin suggest modifying the code which is a starting point, but I'm convinced that we should provide the infrastructure in AbiWord to customize the UI on the use side. Luis Villa provide some insight about Pages from Apple (that I haven't yet had the time to play with), notably comparing toolbar clutter, and how to handle text formatting, points on which dom seems to agree.

Havoc also talks about Pages and how it handles styles; interesting too.

Looks like for 2.4 there is work to do, or to start.
