History: the New Document button makes a document from the selected state

The History panel gets a New Document from State button at its bottom,
which runs the new edit.newDocumentFromState command. The command makes
a new document holding the art of a History panel row ({index?}, the
current state when omitted) and makes it the active document. An index
that names no state is an error and changes nothing.

The new document takes the next Untitled-N name, is marked unsaved, has
nothing selected, no steps to undo or redo and no modified date, and
leaves symbol, opacity-mask and pattern editing; the art drawn in a
pattern's tile is stored in the pattern, as Done stores it. Its links point at the files the
source finds, including files found in the source's folder away from the
links' paths. Those files are looked for only within the folders the
asking caller may read; for a caller without limits, within the folders
the caller that opened the source may read. The source
document, its steps and its saved state stay as they are; typing or a
drag in progress is first kept as a step, as Undo keeps it. While an IME
composes, the command waits, as Undo does.

   - 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.
