I'm so happy to see it doesn't annoy just me. I liked the expanded view as I could see all items at once and it looked tidy, now not only I can't see all at once but it looks more cluttered since all the free slots are in the other tab.
And seriously, why all that added quest items inv space? I think I never filled even a row, even the old one was a load of space, why so much more? It's all really offsetting.
