As the size of the board grows bigger, users will have to scroll all the way down to view more issues. Imagine if the user has more than 1000 issues in a single board, it will be really tiring.
If we can have the configuration to have maybe 2 or 3 issues to be displayed on a single line in the board, it might make it easier. Imagine that the 1000 lines can be cut down into 500. That can save a lot of time.
Perhaps the size of the card can be reduced to have 2 issues to be displayed side by side. That can be a good idea as a start.
