@Giszmo how would replies be threaded? Just a reference to the parent would be sufficient?

@johnsBeharry the nostr kind 1 events already have well defined how to reply to other events. The widget should support replying to specific events and should render stuff accordingly. In my use case I would only show top level events with a :plus: to denote there are replies.
