Why is the additional inventory space only being displayed in additional tabs - and not as a flat increase in inventory space?

Using the expanded inventory view previously eliminated all tabs except the key items&crystal tab which resulted in a simple and clean big inventory.

But now even with the expanded view the additional inventory space is still displayed in a secondary tab - which for me makes it kinda pointless and useless: I eliminated almost every tab by using the expanded view just to have the additional inventory space forced upon me in an additional tab.
