It would be a nice addition to have options which items to track - currently it only tracks desc and price but each other product property is vital too - ref, association, combinations, even shop association, etc. 
	 
	For multi employee shops this is a must module! Thank you for creating it! 
	 
	Also If we can set period for the history it would be nice, a cron that runs xx a week/month to delete any history records older than xx days would be a nice way to automate this.
