Hi @upvu.witness, this looks great and I'm looking forward to trying these new features.

Similar to @future.witness - One idea that could work for saving a draft on the blockchain is to save it within the json_metadata of the user's very first post (apologies if this is the same idea as future.witness). Since the 1st post will always be the first post, then it'll be easy to retrieve and you won't need to record where the drafts are saved anywhere - it'll always be within that user's profile. Since the user's logged in (or needs to be logged in), it's then portable to other devices.

I'm also curious about how the drafts are saved - You mention it's in the user's browser, is this through the use of cookies?
