This feature has shipped.

Ability to do that in the CMS editor urgently needed. Or how can I make use of the API – not without investing in programming, right?

I'm SO excited about this.

It would help if there was a one-click publish option via some sort of app or even a function call.  If you could send a command to a site and publish without having to login, that would save a world of work across many sites updating via Zapier.

Not being able to make simple text updates without re-publishing an ENTIRE site is extremely frustrating, especially if someone is working in designer and another team member is working in editor.

Voting for this, without this feature the api is useless in my opinion as it still needs someone to login and publish the site??? The Api should not have been released without this feature. I have invested money and time into getting a developer to build out a custom module for my company only for it to be completely useless as our clients still have to manually publish everything. Is anyone using the api? I think that many people will not without this feature.

Again, voting for this item.  100+ websites in the coming future all updating dynamically via Zapier so my clients can keep their sites updated themselves

Yes – there should  be the option to 'Save & Publish' in addition to 'Save' for each CMS item. It would be a much faster way of working sometimes.

Or a single page. Any individual change basically i.e.

When you click the publish dropdown, it would show a list of every individual change not yet published for you to (de)select.
