This behavior is currently a known limitation in the Copilot pane UI. The prompt input area is fixed and cannot be manually resized, which restricts the response viewing space on smaller screens. At the moment, there is also no built-in “Copy response” button for individual replies.
Workarounds available today:
- Use the web/desktop zoom controls (Ctrl + “–” or browser zoom out) to increase the effective vertical space.
- Pop out Copilot in supported apps (e.g., Edge sidebar → Copilot → “Detach”) to maximize the response area.
- Use the “Copy” option through the message menu where available (three-dot overflow menu in some Copilot experiences).
- Leverage the Microsoft 365 Copilot web experience, which generally offers a larger and more scroll-friendly layout.
Feature Request Path: Microsoft routes UI enhancement requests through the official Feedback Portal. Users can submit or upvote the request here so the engineering team can prioritize it: https://feedbackportal.microsoft.com/feedback
Documentation Reference: Current UI behavior is aligned with product design documented here in the Copilot Studio interface overview: https://learn.microsoft.com/en-us/microsoft-copilot-studio/authoring-create-edit-topics?tabs=webApp
At this time, dynamic prompt-pane resizing or per-response copy buttons are not configurable features. The recommended path is to file/upvote a feature request so it can be included in a future UI iteration.
Thank you.
