 - **2026-10-23** · `designcraft-cli mcp` takes `--automation-read-root` and `--automation-write-root` more than once, as the suite's other apps do (#1552): a path inside any root of its kind passes, and the roots' common parent, `..` or a link out of them and the other kind's roots stay refused. No readiness percentage change.
 - **2026-10-23** · Layout › Go Back and Go Forward (Cmd+Page Up / Cmd+Page Down, Ctrl on Windows and Linux) retrace the jumps between pages (Go to Page, the page and spread commands, the Pages panel) as InDesign's do, returning to where the view was on each page at the current zoom; a new jump after going back drops the pages ahead, scrolling adds no entry, and pages deleted since are skipped. No readiness percentage change.
 - **2026-10-24** · The Story Editor has InDesign's vertical depth ruler between the style column and the text, and View › Story Editor › Show/Hide Depth Ruler (`view.storyEditorDepthRuler`) shows or hides it in the Story Editor, remembered with the preferences. The ruler is marked in the document's vertical ruler units with how deep the story's text fills its frames, counted through its columns and threaded frames (lines set side by side, in the sub-columns of a split paragraph or on both sides of a wrap object, count once), and is shaded down to the overset point, where a red line now crosses the editor. No readiness percentage change.
+- **2026-10-24** · View › Story Editor › Show/Hide Style Name Column (`view.storyEditorStyleColumn`) shows or hides the Story Editor's column of paragraph style names, as in InDesign, and dragging the bar between the column and the text makes the column wider or narrower (40 to 400 points; the command's `width` sets it too). Both settings are remembered with the preferences, so the editor opens with the same column the next time. No readiness percentage change.
+- **2026-10-24** · View › Story Editor › Show/Hide Paragraph Break Marks (`view.storyEditorParagraphMarks`) shows or hides a ¶ after each paragraph that a paragraph break ends in the Story Editor, as in InDesign. The marks are off until turned on, and the setting is remembered with the preferences. No readiness percentage change.
 - **2026-10-24** · Type › Notes › Previous Note and Next Note (`note.previous`, `note.next`): as in InDesign, they move the insertion point from note to note in the story, putting the caret after the note's anchor. Each item is unavailable when no note lies in its direction in the story, or when the insertion point is in a table cell or a footnote. No readiness percentage change.
 - **2026-10-24** · Type › Notes › Convert to Note (`note.convertFromText {author?}`): as in InDesign, the selected text leaves the story and becomes the text of a new note, whose anchor takes its place; Convert Note to Text puts it back. DesignCraft refuses a selection in a table cell, or one that holds a note, footnote, endnote, anchored object, index marker, text anchor, cross-reference or table. No readiness percentage change.
 - **2026-10-23** · Effects dialog: with Use Global Light on, the Angle field (and the Bevel and Emboss one) stays editable and shows the document's global light angle; a change there sets the global light for every effect that uses it, applied with the effects in one undo step (`object.effects` takes `globalLight`). Before, the field was greyed out and the angle couldn't be changed in the dialog. No readiness percentage change.
