This is the same problem I have.
The CMS user is building a page (i.e. composing the content of a page) in the Content Composer field, by selecting from a number of preconfigured types for a page.
So in the example above, the content of this page consist of:
A text block
An image
A text block
The thing that lacks with this is mainly from CMS user’s perspective. The “Card View” doesn’t give you much of a “preview” of what the content will actually look like.
I asked a similar question here: Controlling appearance in Card View…
If we had more control over what the individual “Cards” looked like for each content type, it would actually make a half decent user experience. Like right now, the card for “Component: Image” is no help, like at all. It’s a blank image placeholder, the text “Untitled”, and the text “No description available”.
