@jstac I have been working on this idea to collapse the warnings issued by code (automatically in our theme). 
This might be a bit too prominent, maybe remove the background colour? But keen to hear your thoughts on this approach (rather than suppression). |

Problem Being Solved
When Jupyter notebooks execute code that produces warnings via stderr, these warnings can be verbose and visually distracting. Example warnings from QuantEcon lectures include:
While useful for debugging, these warnings disrupt reading flow and take up significant visual space. The new feature automatically detects these warnings and provides a clean collapsible interface.
Testing
Once merged, CI will build the lectures with the new theme version to validate:
