Make Appendix Cards smaller on Auto width Dashboards

MichelleH

I've noticed that dashboards tend to show the same number of Appendix cards per row regardless of whether the dashboard's display mode is set to Fixed width or Auto width. When dashboards are set to Auto width, the Appendix cards take up more space because of the additional space available, and in some cases are more prominent than other cards on the dashboard. I'd prefer to keep the cards in the Appendix smaller or fit more per row.
