In the recent 8.18.6 upgrade we lost the ability to collapse multi field items.
This makes it more difficult when editing large multi field items and their containing blocks/pages/etc.
We also can't add groups to multi field items, at least from what we can see when going to settings, which could've been a workaround.
It would be great if you had the minimize/collapse arrow next to the trashcan on each item to help with navigation.
I've attached an image to help show what I mean.
