Expands M365 Copilot Chat and the main Microsoft Loop notes canvas.
A lightweight userscript that expands Microsoft 365 Copilot Chat and the main notes area in Microsoft Loop to use the available browser width, while retaining comfortable padding along the page margins.
Microsoft 365 Copilot normally limits conversations to a relatively narrow reading column, leaving substantial unused space on larger displays. Microsoft Loop applies a similar width limit to the main notes canvas. This script removes those restrictions so that long responses, code blocks, tables and detailed notes are easier to read and edit.
The Copilot page margin is controlled by this line in the userscript:
padding-inline: clamp(12px, 1.5vw, 24px) !important;
The Loop notes area keeps its standard desktop padding. On screens up to 700 pixels wide, the script reduces the horizontal padding to 10 pixels:
padding-inline: 10px !important;
