I would love a custom field card option in dashboards. We have several custom fields that report several important aspects of our business, including costs, drop-down selections, text entries, and even calculated formulas. I have built a tag-centric dashboard and would love to do the same with the custom fields and just have the option to highlight them in individual lists.

For example, for our insurance process, we need to be aware of the cost of repairs compared to our internal estimate against vendors. Having a custom field card option in a dashboard can help gather the total/sum of these two or more custom field entries to help our team see how far above or below budget we are.
