Right now, assistant answers are (at least in my browser), primarily scaled for mobile phone usage. But I use assistant while coding in my browser and about half of my assistant screen is unused whitespace.
See the enclosed image, how much space is wasted and how many lines are unnecessarily wrapped, because the prompt space is too small. 😥
It would be nice, if either the prompt and answer window is scaled with regards to the current window size or the window could be resized manually, to make output code more readable.

I don't think other users would be negatively impacted by this.
