suggestion: add preview of some of the content from each layout when collapsed

I have a flexible content field that is used to construct quite complex variable page layouts in one site i made.

Due to the average page needing quite a few flexible content layouts it means that your plugin is great at not overloading the user with a very deep page of content when they go into edit a page due to the “Collapse all on load” setting.

HOWEVER what the user is left with when the layouts all collapse is just the layout name and due to some of my pages having multiple instances of the same layout, these layout names aren’t enough to go by. What would be great is some way to preview the content of say the first field in the layout inside the collapsed layout title.
