Description of the need If you add an Existing Content block to a layout, you have the option of selecting a specific display mode. This option is NOT available on the "Main Page Content" block and I think it should be.
A user just pointed this out in the forum: https://forum.backdropcms.org/forum/adding-and-using-custom-display-mode...
Proposed solution
I assume that part of the problem is that the main page content is not always a node of a specific content types. Display modes are specific to content types. However, just as you can only select specific field blocks if you have a visibility condition that specifies a specific node type, we could only allow this option under the same circumstances.

Oh thanx ! I had an "old" text format that I had disabled. I re-enabled this format in the field body with the permissions and the field comes back for editing.

I used the theme gin for admin. Perhaps, it's the problem ? I have a color border when i selected the images and of course i used the "ctrl" key.
