Doesn't it benefit steem that the content originates from the blockchain? Could I have that option that I post first to steem then pull that to my site which is just an interface? I read something about the linking not being done correctly so might have to check that but once posted steem will display the content as is? So that canonical thing could be added to the post already? Sorry just rambling in those last two.

Main question is. I would like to indicate/have the content first posted on steem, is this possible?

Import my entire steem blog to my site , sync it?

Option to view the basic markdown version being sent to steem and keep that separate from a proper html version that looks good on the site say when a person uses page builder. Kinda have both, builder for the site, and below that you can check whether you will require it to post a custom markdown version maybe using the parser that steemit uses since it is the only one that has not got some silly hickup with too many things regarding html inside markdown and since most people only use steemit and do not know how things look on busy or steempeak.

Great work though, and you can totally ignore this if none of it is something you would consider.
