[FEATURE REQUEST] Save new post as a draft, publish privately, set a 'time to publish'

I am an avid fan and long term 'investor' into the #steemit platform as an author, curator and 100% 'power upperer' (lol)...

I suggest the need for added functionality which would allow authors to:

1. Save a new post as a draft.
2. Publish privately.
3. Set a 'time to publish'.

Not sure where I should post this.

Is this already being suggested and/or discussed? Is there a specific tag for such suggestions I should be using?

I believe these added features would be well received by the community.

I am sure the devs are already hard at work on this (great to see all the new updates rolling out, well done guys), if not, perhaps they should be? Of course, I understand these things take time, and there are probably other priorities...

I personally, would love to have these features added. Would you?

Is there any type of road-map for added functionality we can see? My apologies if this has already been addressed and/or brought up previously.

The squeaky wheel gets the grease
