I completely disagree with this. Maybe it depends how everyone uses Fibery, but having the important fields shown on top it’s great, especially when doing 2 panel navigation. Notion, Coda etc uses this and for sure they have enough UX data to confirm it, otherwise they would at least try changing it.
2 panels will work really well when you have relationship and you want to check those items, or links to other entities in the rich text, it’s so much easier to open the entity in another panel and keep the view instead of having to go back each time.
