I think this is a feature that really needs to be added.
Currently if you change the bin / Rack of a product there is no way to track this. Its so easy to make a mistake as you have to manually go in to each item to update it or even with an import using good old excel it can easily change a location when you drag down a cell (yes i know i can keep the import file) :-)
It would be far easier to be able to see this like you can on the stock item history report. Would it be so hard to add this functionality.
Seems like it would help many people who have large amounts of stock items to be able to find that needle in a haystack.
