Hello -
Long time user first time poster 
Thank you in advance for considering this feature!
I noticed when using ChatGPT on the Chrome Browser on wide screens the visible chat width (input box and posted questions/responses) is constrained to a narrow center portion that reduces the amount of usable space. This makes the chat vertical length a lot longer and reduces usability especially for long questions and responses. I’ve included an example for reference below:
My request is for this to either auto-expand to the full browser window width or make available a dragger to the user to expand the width.
Best,
Andrew
