ToolBar + Layers + Template

Hello o/

This is not really a feature request but here are some ideas:
(Maybe i need the Template part ^^)

A Tool Bar with news sections “Layers” and “Template”

Layers:
Possible to manage blocks easily, (drag and drop)
Rename, show/hide, copy, direct acces to visibility tab etc

Template:

Here is the idea:

The view change with conditions,

Exemple:
Page: Order details
Statut: Pending → Template 1 with 3 List Details
Statut: Shipping → Template 2 with 2 list Details + block static embeded
Statut: Delivered → Template 3 with an other composition like form feedback,

I think it could be great for loading page when we have a lot of block on same page with this method because we split blocks on different templates, and also for UX for final users with different layout for different situation on the same project

Thank you
