Give the chat more screen space
Ah, I think I see the problem -- aria-label changes according to your language settings, so selectors depending on it won't work for non-English interfaces. I have updated the script to fix this (v2.4), so hopefully it should work for you now.
Thanks for letting me know!
I am impressed by your fast reaction and deduction of what the problem is. I still prefer the other script's show-on-hover approach, but I salute your promptness and confirm that this script now works correctly.
Does not work for me. However, this script does.
