Feature request: More efficient versioning (only keep track of edits)

[JeBy777]

Correct me if I'm wrong, but the way the versioning works right now is it saves all the data from the item multiple times even if some data has not changed, right? Could it be possible to make it so that only the edits of fields are saved and therefore have a smaller impact on performance (and save space in the database)?

Reason I am noticing this problem is because I want to credit the users that modified content but their "versions" get lost because I can't keep all the versions of the item as if even 1 field is changed in a version it duplicates all the other fields too.

Thanks for all the hard work!

The idea is to change behaviour of versioning and create 1 new version per login session, or per e.g. n hours, possibly making this configurable.

About versioning individual fields, that will create complex checks, it will not happen by FLEXIcontent, neither i think that Joomla CORE versioning will ever do such a thing
