The top bar currently occupies space even when someone is reading. Add a toggle before Undo that hides the entire bar, including docked table controls, and releases its height. The 01md logo remains available to restore it, with no button background or shadow, including on hover.

Behavior

• Add saved, live-updating preferences in VS Code and Electron for the default logo or double up/down chevrons, and optional hover-only visibility while hidden. Hover-only is off by default; keyboard focus reveals the button and touch devices keep it visible. Reduced-motion preferences disable the fade.
• Keep collapsed state within the current editor session, independently of Full/Simple mode and Contextual tools. Preserve content, selection, active equation input, editor mode, and undo history.
• Close anchored menus when hiding the bar and retain recoverable keyboard focus, including from Export and docked table navigation. Keep the toggle reachable after resizing and restore toolbar overflow correctly.
• Update all seven interface/settings locales, desktop logo packaging, documentation, and regression coverage. Settings tests continue to enforce the exact supported contract.

Validation

• Full compilation and Electron TypeScript check passed.
• Focused Chromium regression: 137 passed, two workers, zero retries, across toolbar visibility/discovery/command search, table toolbar rows/overflow, Export, and Preferences. Includes all seven themes, narrow panes, touch, keyboard recovery, selection, and Undo/Redo.
• Complete unit suite: 468 passed, 19 skipped; real-converter/package prerequisites were not enabled.
• Lint: zero errors, 11 existing warnings.
• Documentation/link checks and git diff --check passed. Reviewed the complete changed Markdown files in source and a local rendered preview.

Native installed VS Code and Electron launch checks have not been run locally; browser fixtures exercise both production HTML generators. Remote CI results remain separate from these local results.
