Currently content apps (and pages app in particular) don't provide information on creation date etc. to editors. This is a very basic requirement for teams working on the same content ("who created this page?", "who modified that page I created?")
Currently the only way of finding out is to export the nodes as XML and go looking for mgnl:createdBy tags etc., nothing you can expect from an average content editor.
How about a little panel in the bottom right corner that provides these details, similar to the "Preview" panel in the DAM?
These would be:
- Created by (user)
- Creation date
- Last modified by (user)
- Last modification date
