Such workflow is not implemented in the blog section. All posts are published directly, although they do not have to be published immediately (you can set the publish date in the future).

Thanks denis - Is this feature will be added in the roadmap anytime soon?

You can vote for it in the roadmap forum. In its simplest incarnation, it would could just be used to disallow "ordinary" blog editors to directly publish the posts, and allow only users from the admin or another custom group to subsequently publish them.

Hello MonoX team,

Was this feature considered for 4.7 version ?

anyone ?

This will not be implemented in the next upgrade. We will listed to the community, as we did not recieve any additional requests for these features. Note that they are not trivial to implement, so there has to be more feedback if we are to reconsider implementing it for 5.0.
