 # Restore Jumpbox
 
-A development extension that restores the public forum jumpbox on prosilver forum and topic pages after the removal proposed in [phpBB PR #6927](https://github.com/phpbb/phpbb/pull/6927).

-For testing on phpBB 4.0 with the removal applied, place the extension in `ext/phpbbmodders/restorejumpbox` and enable **Restore Jumpbox** in the ACP.
+Restores the public forum jumpbox on phpBB 4.0.
 
-In **ACP → General → Load settings**, set **Show the public jumpbox** to **No** to hide the selector while keeping its permission-filtered links available to phpbb-tui.
+phpBB 4.0 removes the "Jump to" forum selector, as proposed in [phpBB PR #6927](https://github.com/phpbb/phpbb/pull/6927). This extension puts it back on prosilver's forum and topic pages.
+
+## Features
+
+- **"Jump to" selector** at the bottom of forum and topic pages, listing only the forums the visitor is allowed to see, in board order with subforums nested.
+- **Show the public jumpbox** setting under **ACP → General → Load settings**. Set it to **No** to hide the selector while keeping its forum links in the page for clients that read them, such as [phpbb-tui](https://github.com/drdewes/phpbb-tui).
+- Keyboard support: Escape closes the open selector and returns focus to its button, and screen readers are told whether it is open.
+- Steps aside on phpBB builds that still have their own jumpbox, so the board never shows two.

+## Requirements
+
+- phpBB 4.0 (4.0.0-a2-dev or later in the 4.0 series). phpBB 3.3 still has its own jumpbox and does not need this extension.
+- PHP 8.2 or later
+- The prosilver style, or a style based on it
+
+## Installation
+
+1. Copy the extension to `ext/phpbbmodders/restorejumpbox`
+2. In the Administration Control Panel, go to **Customise → Manage extensions**
+3. Enable the **Restore Jumpbox** extension
+4. Optionally change **Show the public jumpbox** under **General → Load settings**

-# Initial scope
+# TODO
 
-[phpBB PR #6927, proposed revision 5f96997](https://github.com/phpbb/phpbb/pull/6927/files), removes the public jumpbox and its ACP load setting on the 4.0 development branch. It retains the Moderator Control Panel jumpbox and the forced-display path in `make_jumpbox()`.
+The first milestone, the selector on prosilver forum and topic pages with an ACP visibility setting, is built. These items are still open.
 
-## First milestone
+## Before declaring phpBB 4.0 compatibility
 
-- Restore the forum selector on prosilver forum and topic pages. Treat other removed placements and the old “Return to” links as follow-ups.
-- Use phpBB events and an extension-owned template. Confirm that the target 4.0 revision supplies suitable events and that the retained helper can populate the public selector with the current visitor's permissions.
-- Preserve the category order, nesting, forum URLs and anchor classes parsed by [phpbb-tui](https://github.com/drdewes/phpbb-tui). Its fallback checks forum pages linked from the index, so an index placement is optional for the first milestone.
-- Verify that enabling the extension restores the selector and disabling it removes it. Leave the core ACP setting and removed search-results event outside this milestone.
+- Recheck the final diff of [phpBB PR #6927](https://github.com/phpbb/phpbb/pull/6927) once it is merged. This extension was built against revision 5f96997; if the merged version keeps different events, template variables or `make_jumpbox()` behavior, adjust to match.
+- Recheck against phpBB 4.0's new default style when it replaces prosilver. The templates here are prosilver only.
 
-## Acceptance checks
+## Other places the removal touched
 
-- On a phpBB 4.0 test board with the removal applied, verify nested navigation on forum and topic pages for a guest and a signed-in user. Check that restricted forums are absent for users who cannot list them.
-- Run phpbb-tui against the board and compare its forum tree with the permitted hierarchy, including nested forums missing from the index. Check the Moderator Control Panel selector with the extension enabled.
-- Recheck the final upstream diff and supported style before implementing or declaring 4.0 compatibility.
+PR #6927 also removes the jumpbox, or the "Return to" links next to it, from these pages. Bringing it back on any of them needs a suitable template event; where core has none, write the request for one under `docs/events/`:
+
+- Search results
+- Posting, the forum login page and the FAQ/help page
+- Memberlist, team page, user profile and Who is online
+
+## Ideas
+
+- An index page placement, for clients that cannot reach nested forums from the board index.
