File versioning plugin

Hello there! 

Let me start by saying how impressed I am with Elgg. What a hidden treasure it has proven to be :)

I was wondering if anyone knew of an existing plugin which gives the functionality to keep a history of a file. Say someone wrote a document, but another user improves upon it, they should be able to upload the new document while still keeping the old document as a previous version to revert to in case of negative feedback.

Again, majorly impressed!

Best regards
