 ## Progress log
 
+- 2026-11-04: New Document: the units chosen in Preset Details now belong to the chosen document, as the pane's options are listed for the selected preset; the chosen card shows them, every other Recent and Saved card keeps the units its document or preset was made in, and the built-in tabs still follow the chosen units, so switching between inches and millimetres no longer restyles every recent template. Scores and estimates unchanged.
 - 2026-11-02: Mouse wheel over a closed font-family field in Character, Properties or Control changes selected text through the family list using saved font filters (excluding search text), one undo step per notch, stopping at the ends (#5253). Scores and estimates unchanged.
 - 2026-10-31: Pattern libraries: Window › Swatch Libraries › Patterns and the Swatches panel's library menu open Geometric Patterns, a built-in library of eleven pattern swatches (dots, stripes, checks, a grid and shapes); clicking one adds its pattern and swatch to the document, once, and applies it to the active fill or stroke (`swatch.library.add`).
 - 2026-11-01: Find Nearest Swatch joins the Color Effects add-on (Object › Plug-ins › Color Effects): for each colour of the selection, the closest swatches of the document, a built-in library or a library or colour book the user loaded, with their CIEDE2000 difference; Apply gives each colour its nearest swatch as one undo step, linking global and spot swatches and adding a library's to the document first, so a process colour becomes the closest spot colour (`addon.color.nearestSwatch`, `addon.color.applyNearestSwatch`, #4923).
