Are you setting a density in the framework? It looks perhaps like the image is using Spacious density - if so, the difference is likely the introduction of density-related spacing in 13.0.
perhaps it would help then if you could explain how to disable this or reduce the padding in the rotateHeaderTitles-docs.
I don’t think that it’s possible to do this somehow via resizeControls just for one ListGrid, correct?
There are already defaultDateFieldWidth and similar properties for Date-field widths, but non for boolean fields. I assume that boolean fields will be the main use case for rotateHeaderTitles: true.
