# UnifiedWriter v5.64.3 Menu / Outline Polish

## Purpose

v5.64.3 is a UI-polish fix on top of the v5.64 Control/Host integration standard. It does not change the Model-first editor architecture, the EditorControl edit/view mode contract, or the Host File menu delegation policy.

## Fixes

### 1. Format / View menu geometry

Japanese Format and View menus previously reserved too much empty right-side space before submenu arrows or shortcut metadata. The Workbench shell now applies a final compact menu geometry override that:

- keeps icon / label / shortcut / caret columns stable;
- caps the label column with ellipsis instead of expanding the whole menu;
- narrows shortcut and caret metadata columns;
- keeps nested submenu popouts visible outside the root menu.

This is a Workbench chrome fix only. It does not change command execution or document data.

### 2. Outline de-duplication

When WorkbenchControl shows the left pane, the left pane is the primary Outline location. The right utility pane therefore starts with Search/Replace and does not render a second Outline tab.

When the left pane is not used, the right pane can still include an Outline tab, preserving a compact embedding option for Hosts that hide the left pane.

## Host integration rule

OneEditor and OneViewer normally embed `EditorControl` directly and compose their own UI. WorkbenchControl is only a reusable body+chrome surface. The v5.64.3 changes are therefore limited to Workbench UI behavior and do not impose menu layout on OneXXX Hosts.
