Please accommodate desktop users with a wider text area

Not a “bug” as such, but ChatGPT’s mobile-first design is really “mobile-only” in that it wastes an enormous amount of screen real estate with useless whitespace. Worse, the horizontal scroll bar that’s often needed to view code-based responses doesn’t always appear; see example attached. Please consider adapting the main ChatGPT page to support users with actual PC monitors, not just phones. Thanks!


Thank you for your feedback.
Please change it to a feedback tag in order to distinguish it from actual bugs.

Hmm, the ‘edit’ button only seems to offer these options:

I don’t see a way to change any tags, and it already appears to have the “chatgpt-feedback” property. Let me know how to do what you’re asking and I’ll give it a shot.

That said, arguably failing to show a horizontal scrollbar on that window is a legitimate bug.

I apologize for the confusion. I have updated the tags for you. Please understand that there are more serious bugs in ChatGPT, so I’ve adjusted the tags to reflect this as feedback.

I understand that the text display area is narrow even though the desktop screen is wide.
I would like to think of the best ways to encourage them to improve, but the current situation is that there is no other way than to show it as feedback in the appropriate form here.

Your feedback should never be taken lightly, and I sincerely hope that it will be handled appropriately.

Here’s a Tampermonkey script, for the tampermonkey or greasemonkey browser extension. It also changes some other visuals, but you can “monkey” with the internals.
