   - Edit › Undo and Edit › Redo, in the in-window and native menus, name the step in the interface language as the History panel lists it (`panels::history::step_name`), so when the catalog has no plain row for a step named after an effect, such as Feather, the menu shows the translation of the effect's menu row without its ellipsis (`undo_and_redo_name_the_step_as_the_history_panel_does`).
   - The History panel translates the undo step names the engine, the tools and the shell write as literals: the untranslated report (`untranslated_report`) lists any a complete catalog lacks, and a step whose catalog row exists only with an ellipsis (such as an effect's menu name) shows that row without the ellipsis.
   - The German catalog (`crates/ui-egui/src/i18n/de.tsv`) has an `@msg` row for the status and error messages the untranslated report (`untranslated_report`) finds in the sources, 3,433 `@msg` rows in all: the errors of commands, scripts, file import and export and plug-ins. The report lists 48 German messages; 38 of them are the composite font, select-a-path and justification order errors that open #7211, #7214 and #7116 translate. A message with two placeholders in a row (`Template::parse` in `crates/ui-egui/src/i18n/catalog.rs`) is still shown in English.

The untranslated report (`untranslated_report`) still lists 1,867 Korean messages, which are shown in English.

   - The History panel menu has Step Backward and Step Forward, which run Edit › Undo and Edit › Redo and are disabled when there is no step to undo or redo, and Set History Limit…, which opens Preferences at Performance, where History States is set.
   - The History panel menu's Clear History (`edit.clearHistory`) removes every step to undo and to redo and leaves the document as it is; it is not an undo step itself, and it is disabled when there is no step to clear.
   - The New Document from State button at the bottom of the History panel (`edit.newDocumentFromState`) makes a new document, which becomes active, from the state the panel has selected ([public source](https://helpx.adobe.com/illustrator/desktop/get-started/learn-the-basics/undo-edits-and-manage-design-history.html)). VectorCraft's own rules: the new document takes the next Untitled-N name, is marked unsaved, has nothing selected and has no steps to undo or redo, and the source document and its steps stay as they are.
