As far as I know there's no draft mode at the page level, but can be implemented with page attributes. This is fine, but I would love to be able to see the page's status on the page listing in the control panel.
Are there plans to adding a draft mode to pages? I like the various highlights added to a region when it is saved as a draft (pencil icon, preview button, a bar on top of the edit form). It would be nice to see this at the page level too.
Alternatively, I would like to be able to add a column to the page listing from the page attributes template (like in Collection listings).
I think this would make it easier for editors to manage pages and spot which pages are published/drafts.
