 - **2026-10-19 (M3, #3387):** Save-prompt shortcuts yield to later consent and utility dialogs; a synthetic UI regression checks that an edited document stays open. Estimates unchanged.
 
+- **2026-10-18 (M3, PR #3101 review):** Gap changes in Organize Pages preserve document scroll position; menu and control changes apply to both comparison panes without changing unrelated tabs. Three synthetic UI regressions were observed failing before the fixes. Readiness estimates unchanged.
+
+- **2026-10-18 (M3, PR #3101):** Optional gapless continuous page display with persisted defaults and UI control support; both new labels translated in all 22 catalogs. Rebased onto current main, preserving navigation and rendering fixes. Readiness estimates unchanged.
+
 - **2026-10-18 (M10, #3120):** Export to Word, PowerPoint, HTML and RTF reads text from form XObjects nested as deep as the renderer draws them (50 levels), and up to 50 000 forms a page (the renderer's budget for nested ones); it stopped at 12 levels and 4 096 forms and left the rest out silently. A page past those limits is listed in `doc_export_office`'s `truncated_pages`, with a warning. Estimates unchanged.
 
 - **2026-10-18 (M5, PR #1971 review):** Nested FDF annotation values that identify a source `/Page` or `/Pages` dictionary become null at every copy depth. A synthetic three-page PDF saved and reopened before export verifies that destination actions cannot pull source page content into the FDF, while unrelated nested metadata and shared references remain intact. FDF import semantics, copied-graph limits and estimates are unchanged.

+# Continuous page display
+
+> **Last updated:** 2026-10-18 · Viewer: optional page gaps.
+
+To read pages as a continuous strip, open **View → Page display**, choose **Single page**,
+turn **Continuous scrolling** on, and turn **Show gaps between pages** off. The Page display
+button on the viewer rail opens the same choices. The command palette also offers
+**Show gaps between pages** as a toggle.
+
+Hiding gaps joins the displayed page edges and removes page shadows. It does not crop or
+change the PDF: white margins already in a page remain. Pages of different widths stay
+centered. In two-page view, it removes both the gutter within a row and the gap between rows.
+
+For future documents, open **Preferences → Documents and view** and uncheck
+**Show gaps between pages**. This default survives a restart. Existing documents retain their
+current view; the per-document toggle does not change the preference for future documents.
+
+Desktop launch options:
+
+```sh
+pdfcraft --layout continuous --page-gaps off document.pdf
+pdfcraft --default-page-gaps off
+```
+
+The opt-in UI control channel accepts `set key=page-gaps value=off` for the active document
+and `set key=default-page-gaps value=off` for future documents. Its `command` method accepts
+`id=view.page_gaps`, and `state` reports `active.page_gaps` and `active.continuous`.
+
+Revision history: 2026-10-17 — added local gapless-display controls and documentation.
+
+In a side-by-side comparison, the gap setting applies to both panes. Changing it in
+Organize Pages keeps your document scroll position when you return to the viewer.
