Why does the new inventory UI show less items on Expanded than before?

[Sindele]

With the new 5x7 layout, the inventory, armoury chest, and saddlebag all share a unified interface. And with four bags instead of five and a half, sorting by tab works a lot better. Also the item search feature now specifies the correct tab while using the expanded layout.

Except for my 8 retainers, who now all have an interface that went up by a page in total - an awkward half-page at that. Very unified.

Also, /isearch specification was actually *more* accurate before once you got over the initial hump of figuring out how it was numbered. All it tells me now is that it is somewhere in a vague mass of 70 items, marking yet another loss of granularity.
