I'm in the middle of something else (more metafunish) so didn't follow 
this thread but normally Pablo comments on it ... widgets are a bit of a 
pain (ended up in the pdf spec before supported, bugs that became 
features - esp defaults - parent/kid issues and differences between 
viewers, appearance streams, etc). The same for some annotations that 
basicaly got dropped. It has always been about adapting to observations.
