Can a button be added to hide the sidebar? it would make browsing easier to use when many columns are enabled (for e.g. on Traces).

Thanks for the suggestion @samyxdev. Agree, this would be super nice as especially the single trace view would benefit a lot from more horizontal space on large screens.
