Hello!
I want display 'body' block from composer in page type.
I add 'Composer control' block and set 'body'.
Save page type.
I see "The Body page type composer form element will output its contents here (Block ID 308)" when i created new page and saved it.

All right If my template has 'Main' area. 'Body' displaing automatically in 'Main'.
But if my template do not has 'Main' area:
1. Enable theme with main area
2. Delete 'body' composer block from content type
3. Enable my theme without 'Main'
4. Add composer 'body' block.

Many steps.
So it should be or is there an easier way?
Sorry for my english. I hope you understand me.
