With the addition of collaborative editing, iterative edits cannot be done without also publishing the content. In addition, publishing the content with multiple users making edits will publish incomplete content.

therefore, here are a few improvements that may help improve the usability and the intuitive nature of collaborative editing:

1) It would be really nice if there were a way to view the diff from the last published version of a page to the current draft status. That way it would be much easier to undo changes without potentially having to publish and then revert unintentional changes.

2) The old "Discard Draft" functionality did warn before discarding others changed IIRC, it would be nice if the Update/Publish button could do the same if there are multiple people editing.

3) Relying on undo/redo while editing makes sense, but it appears that the Redo keyboard shortcut is Cmd+Y on Mac which is the Windows standard Redo shortcut with Cmd swapped for Ctrl. It would be nice if the shortcut could be made Cmd+Shift+Z for Mac clients since that is the standard Mac redo shortcut.

4) It would be nice for changes that users are making to be highlighted so that you can see who is making what changes.
