The search.pl page shows results for items, but only shows the cart location, if used, for the item location. Librarians want a quick way to locate items, and removing the permanent location forces librarians to click into records to see the permanent location. Cart locations should show next to the permanent location, either emphasized or in parenthesis. But wherever a shelf location is shown, permanent location should always show, and the cart location should be added to it in some discernable way.
Agreed, that replacing the item's permanent shelf location is not timesaving when trying to locate an item. If a "recently returned" STATUS could display for a set period time and leave all location information for the item intact, that would be helpful!
