The ability to include barcodes in inventory count printouts.
Alternatively, the ability to merge inventory counts.
At E Ride we have multiple different sections of the shop which don't need to be separated in lightspeed, but are too large to count concurrently. The ability to merge inventory counts, or even include barcodes in our itemized lists, would streamline this process greatly. The former may be a little far-fetched, but the latter already exists for inventory transfers.
