Would it be possible to add functionality to this plugin to allow a Super Admin of a Multisite see when changes to their sub-sites have been made? (Changes including but not limited to posts, pages, widgets, settings, themes etc.) The reason I'm requesting this functionality is to see when I need to make a new backup. If that is not possible with this plugin, would you be so kind to point me in the right direction for a plugin that does do this (if you know of any)? Thanks so much!
