Keep History for each action

[tayfunyasar]

It would be great if we log every action for each item.

For example,
Who and when is changed the key or value, added, updated it.

Another action might be about restoring it from history.

Thanks.

That feature is key!!

History of translations and terms and the ability to revert.
