Currently, on a board of next-gen project, the cards only show the icon of the issue type, the issue summary, issue key and the assignee's avatar.
It would be great if we could customize the card to add more helpful information, such as priority. For now, we must click on the card to open the issue and check the priority.
We already had a response on JSWCLOUD-17268 saying that there are plans to add priority in the backlog, but it would be nice if priority is also added on cards.
