Thanks - I'll take a look.

I totally agree - I'm not proposing to get rid of the 
beforeAnnotationCreated event, I still plan to use that event, too. If 
it doesn't muck up the core code too much, I'd just like to see an 
"in-between" event, such as beforeAnnotationStored. Maybe it would make 
sense for this event to be called from the store (Store, NullStore, 
WhateverStore) class itself instead of the core, as it might be 
something more specific to the store? Not sure.

In my use case, I present the UI based on the annotation, but then I 
need to retrieve / format data entered in the UI to formatted annotation 
data after the user has modified the UI. My UI doesn't directly 
translate to the annotation object, so I have to have hooks to convert 
data to the UI and convert values in the UI to data before the 
annotation is stored. Sorry if that's not clear, maybe a diagram would 
be better :)
