 - **Dragging a document tab out and a document window back (G7):** a document tab dragged more than 24 pt above or below the tab strip floats its document in a window under the pointer, and a document window dragged onto the tab strip goes back under the tabs ([public source](https://helpx.adobe.com/illustrator/using/customizing-workspace.html)). A window inside the app's window is dragged by its title bar; an OS window by the document's tab at its top, and the window follows the pointer. The 24 pt distance and the tab at the top of an OS window are VectorCraft's own. Tests: `crates/ui-egui/src/doc_windows/tests.rs`.
 - **Reordering document tabs (G7, #5663):** a document tab dragged along the tab strip moves its document among the others ([public source](https://helpx.adobe.com/illustrator/using/customizing-workspace.html)); a line marks the gap it goes in. The current document stays current, each document keeps its own zoom, centre and artboard, the views Window › New Window opened move with their document, and Window › Next/Previous Document follow the new order. `document.move` (`{from?, to}`) does the same from MCP, the control channel and recordings. `crates/ui-egui/src/tests/tab_reorder.rs`, `crates/engine/src/tests/document_move.rs`.
 - **Closing a background document tab:** closing a tab other than the current one (`file.close {index}`) keeps the current document current, and its tool keeps its state; closing the current tab still makes its neighbor current. `crates/engine/src/tests/document_close.rs`.
+- **Replacing a background document's content:** `Session::replace_document` on a tab other than the current one (the replacement File › Revert makes for the current tab) measures the new content's type in that document's own composite fonts at once, so that type has its measured bounds while the document is in the back. When that document becomes the current one unchanged, its type in those fonts is not measured again. `crates/engine/src/cmd/compositefonts/tests.rs`.
 - **Export and Import Preferences (#6435):** an optional VectorCraft feature. The Preferences dialog's Export Preferences… saves the applied preferences to a JSON file (`prefs.export`; the web build downloads it), and Import Preferences… applies such a file (`prefs.import`). The file leaves out the folder preferences. The import checks every value first and changes nothing on an error; it keeps the open document's units and records no undo step. The file format is VectorCraft's own. Tests: `crates/engine/src/tests/prefs_file.rs`, `crates/ui-egui/src/prefs_dialog/tests.rs`.
 - **Preferences › User Interface › Open Documents As Tabs (G7, #394):** checked by default, documents open under tabs in one document window ([public source](https://helpx.adobe.com/illustrator/desktop/get-started/learn-the-basics/workspace-overview.html)). With the box cleared, each document opened or created afterwards opens in a floating window of its own, at the next cascade place, as Float in Window floats it; documents already open stay where they are, and checking the box again leaves floating documents in their windows. Tests: `crates/ui-egui/src/doc_windows/tests.rs`.
 - **Preferences search:** a Search Preferences field above the category list has the keyboard focus when the dialog opens, and Cmd/Ctrl+F gives it back; typing lists the settings it finds, and choosing one shows its category, as the [help page](https://helpx.adobe.com/illustrator/desktop/get-started/preferences-and-settings/set-app-preferences.html) describes. VectorCraft's own rules: the field matches a setting's label, section or category, ignoring case, in the interface language or in English; the list replaces the categories while the field has text and shows every match, or "No settings found"; the chosen setting's row is highlighted and scrolled into view; Escape in the field with text clears it, and Escape in the empty field closes the dialog. The dialog's `__search` field (`ui.dialog.set`) holds the text. Tests: `crates/ui-egui/src/prefs_dialog/tests.rs`.
