Edit history / retaining of information
In Zotero Groups, we have noticed that "added by" information only registers the last person modifying an entry; the reference to the user who has originally uploaded the entry seems to disappear. Is there no function in Zotero to see the "history" of an entry?
I would also think that if this info is stored, exposing it to user interface would be nice. (And in the server API too.)
The editing user isn't particularly reliable at the moment, which is why it's not displayed or provided via the API. Once we make sure it's more reliable, we'll display that as well (and probably make it available to the Zotero client).
