Key change about the new interface that is 100% not the same as it was before: it opens an entire screen-covering interface that you can't see around- no chat, no game messages, nothing - and it smashes two things that were completely different together to free up a tab. You straight up have to interrupt everything you're doing just to navigate them, whereas before you didn't with the quest system and, to a lesser extent, tasks. I thought that was pretty clear what n64 meant.
