When an item set is managed by numerous people, it would be useful to know what has been modified, when, and by who. This feature is very useful in any collaobrative tool, such as a wiki. It would also be very useful in Omeka S.
This is an important feature indeed. In Omeka Classic, I built the plugin History Log to keep track of any change, and to be able to revert if a trainee does something wrong, but it is not upgraded yet.
