I really like using the kanban view, for some use cases, it would be great to fit more information onto the cards while keeping small enough so a kanban row does not grow too long and you can get an overview of the data. Some information would fit in two columns for example especially on the card size settings M and L. A solution for me could be additional sliders for the card size menu, one that changes the font size and one that changes the margins between the fields. Another option could be an overall board zoom. I am not sure what would be a better user experience.
