I've mentioned this a few times now- 

WHY can't you implement a full width search option? Whenever we do a purchase order or input/edit an order the window is WAY TOO SMALL. We have the whole width of the screen available, but it is crammed in a corner that makes us have to slide the divider to try and see the sku or title for every item we input. Or give the option to remove headers (level, due etc)

SO frustrating when we have many similar sku's.
