I love how you make the console output update turn by turn but I think “Console output” ,especially stderr, is too small and too narrow. This make debug unnecessary harder.
Please add things like
- a button for copy all text to clipboard
- a button for expanding windows that make me see more output content
- sync both code and output (chrome sync addons)
What’s wrong with the current one?
It was pretty narrow already in single-player problems. Having to share it with the opponent list makes it even worse in multiplayer. Especially when we don’t have a way of selecting how wide they should be relative to each other (e.g. the way it’s done between the left (viewer/text) and right (code/control) views.
Our screens are obviously not as wide as your designer’s 
It only expands vertically.
copy to clipboard seems an easy fix for an annoying problem. +1
