We're just going through to do our physical inventory for the 1/2 year point, and I noticed a very nice improvement in the UX for Inventory Adjusts.

Now, when you change the date to do an adjust for a previous day, the middle section recalculates to show the inventory status on that day.

It was always a minor annoyance not being able to see the item's status on the day in question, so this is a great improvement.
