Add missing command palette commands to menu bar and reorganize into logical groups: File, Edit, View, Go, Note, Vault, Window. New menus expose navigation filters, note actions, vault management, themes, and git operations. Context-sensitive items (archive, trash, diff, raw editor, commit, conflicts) are greyed out when not applicable. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
