editorLayout

# recording.editorLayout/layout.yaml
title: Recording      # the name the layout switch shows
title_key: layouts.recording.title   # optional: a catalog key; the switch reads the title from the catalogs in the editor's language
description: The scene and the first agent's terminal side by side.
description_key: layouts.recording.description   # optional: the same for the description
slot: a               # optional: a | b, the side of the layout switch this layout stands for until a person assigns another
mode: full            # full | simple: simple keeps the layout's panel set; a panel that registers later waits in the Window menu
toolstrip: shown      # optional: hidden takes the gizmo buttons, who-is-here counters and live indicator off screen
panels:
  - { id: viewport, dock: center }
  - { id: agent, dock: right }
fractions: { right: 0.42 }

The editor switches between two layouts, side A and side B. A layout declaring slot: a or slot: b is what that side stands for until a person assigns another layout to it; the shell keeps the person's choice per world on their own machine. A world layout of the same name stands in for the built-in one.

title_key and description_key name catalog messages, looked up in the world's locales/, then the editor's own, then the library's. While a catalog holds the key, the Window menu and the layout switch show its message in the editor's language; otherwise they show title and description as written.

A layout the editor ships lives in the built-in library; one a person saves lives in the world at /zero/source/editor/layouts/. Both are the same asset, and a world layout of the same name stands in for the built-in one.

In the Inspector

Layout: the layout's title, description, switch side and mode, whether it carries a captured dock, each panel it places and where, and Apply layout, which arranges the editor this way (and says why when it cannot).
