Changing an item's length in amount of positional squares isn't infalible. There will certainly come times when the positioning will make it so the player has to readjust things to take advantage of unused space, and when that happens he still has to deal with items which occupy a given amount of space which would be better occupied if the item was in a different position. In those cases, a simple method of Alt+clicking an item to rotate it would allow for items to be placed differently (while still occupying the same number of slots or squares) in the pack.
