I have a project with a single board. The board has five columns and several lanes based on components in the project. When I display the board on an external monitor, like a large TV, the divisions between columns and lanes become very washed out so that it's not possible to see them. Is there a way to modify the graphical elements of a board, for example adding borders between columns and lanes or changing the column background color? I think of this as modifying the theme applied to the board. I've looked through project settings and system settings, but nothing is jumping out at me as applying to boards. I also did a quick look through possible add-ons and didn't see anything. Thank you for any assistance.
Regards,
