When you first add your library collection, it would be great to say where the location is (for the bulk scan) . So each time you bulk scan you should be able to put the location in. Also, there should be a sound when it's a dupe... And, if you have a similar title it would be nice to flag it /verify that in the search to prevent dupes. And to be able to use your flashlight or phone flash to read barcode's in dark places
