Don’t want to publish all of your posts at once but hate manual scheduling/rescheduling? Post to Queue comes as a solution. You just put posts to queue and they’ll be published automatically when chosen time passes since last published post of that post type. It’s even possible to choose days of the week and hours of the day when those posts will be published.
Post to Queue is like Buffer for WordPress, just better.
It requires that cron runs regularly to be able to publish posts on time.
Post to Queue code is partly based on a code from plugin <a href="https://wordpress.org/plugins/automatic-post-scheduler/" rel="ugc">Automatic Post Scheduler</a> by <a href="http://tudorsandu.ro/" rel="nofollow ugc">Tudor Sandu</a> and a code from plugin <a href="https://wordpress.org/plugins/metronet-reorder-posts/" rel="ugc">Metronet Reorder Posts</a> by <a href="http://www.ronalfy.com/" rel="nofollow ugc">Ronald Huereca</a> and <a href="https://geek.hellyer.kiwi/" rel="nofollow ugc">Ryan Hellyer</a> for <a href="http://www.metronet.no/" rel="nofollow ugc">Metronet Norge AS</a>.
