What does your feature entail?
I'd like to have line numbers for Assistant code output enabled. I did check whether I could just enable them with custom css and by looking at the assistant with browser developer tools, it seems like the markdown converter used for assistant already supports linenums, but it needs to be enabled server side.
What are the exact ways that you see a user using your proposed feature?
Code block output with assistant is handy as it currently is, but the first output often isn't as expected. Asking the assistant to improve or explain the result would be easier if I could just ask it to explain/change something on line X, instead of describing the position with words. I'm sure there are many ways in which line numbers are useful for code output, for me it would increase convenience so much so it's worth asking.
