I got ChatGPT to help patched sdkjs/word/sdk-all.js so ‘Multiple Pages’ becomes a single horizontal strip, with normal mouse-wheel scrolling mapped horizontally. Editing still works normally. This is very handy if you are viewing multiple pages on an ultrawide monitor. Would be great if this were incorporated as a feature in a future release.
(I would include the js file for others to use but don’t know how to upload it).
