Page preview - what does it do and where is it?

What does the “preview” do?

I was imagining it would preview the page, in the Panel, before making changes live. But I can’t see a Preview button anywhere in the Panel

I have preview set to true:

title: Default pages

options:
	preview: true

tabs:
	tab1:
		label: Content
		icon: page

But no Preview button in the top right of the Panel

The preview button is the one on the left in your screenshot, with the arrow outside the box.

However, with v4 it cannot preview any unsaved changes, so its preview function is currently limited to page drafts. Saying currently as we would like to change that in an upcoming release.

Oh, the link to the live page – got you.

Thanks
