Does exactly what you want

I’d love to see WordPress’ official revisions, scheduled publish dates, draft management, etc. be extended to allow for scheduled updates to already-published content. Until that comes to be, this is definitely the next best thing that does what you’d want it to. Bonus that it’s listed on GitHub for community support, suggestions, fixes, etc.

I’d think this plugin would get much more use & adoption if the listing was given a few refinements (the public plugin name isn’t all that friendly, doesn’t have an icon or banner, could use a few more screenshots [the animation is nice, though], etc.) That doesn’t really reflect the usefulness or quality of the plugin. Think it makes for why something so potentially useful for so many sites doesn’t have as many active sites using it at the moment.
