We would need to show 4 custom fields on kanban card. JIRA Agile now only allows 3. We have a few important calculated custom fields and we can't show them anywhere on the kanban board as the details view does not allow calculated fields to be shown and we have already used the 3 slots on the kanban card.

Actually, we would prefer showing some of the calculated fields on the details view, so if https://jira.atlassian.com/browse/GHS-10191 gets implemented then this is not so critical.
