We considered that, but our sense was that trying to do something like that would significantly increase the scope of the feature and also require us to consider additional edge cases in the user experience For example, if it’s a post in an existing topic, maybe the conversation has moved on by the time you’re revising it… And for new topics we still have our “1 draft at a time” limitation that could come into conflict with that workflow.
So for this iteration, we landed insetad on stuffing the contents in the private message so it can be copied and pasted.
