Problem/Motivation
The block listing in Layout Builder is a little overwhelming for users. When adding a block to a Standard profile Article, there are 59 block plugins in the list. You can imagine that with contrib enabled this list would become even longer and more irrelevant for the majority of users. It looks like this, currently:
Proposed resolution
By default close all categories except for the entity type categories which contain the field blocks.
Inside the entity type categories move all of the non view configurable fields, anything that doesn't show up on the "Manage Display" page of the Field UI module, into a subsection labeled "More",
Here is the listing when it is first opened
Clicking "More" will show the other fields for the entity type.
