And awesome, a deleted post doesn't even show up in the API. That makes that part easier.
I think the only other major things are handling polls and maybe displaying a count of boosts/replies/favorites, when applicable. I'm definitely not going to try to handle interacting with a poll from the widget, as that would entail some login shenanigans I'm not really prepared to deal with at the moment. Still, usefulness abounds!
