We can customize most cards: Initiatives, Release, Features, Requirements, and To Do, but we cannot customizer the Ideas.
It would be great to have the ability to customize the detail card of the Idea similarly to have we can customize other detail cards. This would be useful when creating a Kanban view of Ideas.
Thanks for the idea! Could you tell us more about how you are creating a Kanban view of ideas, or how you would like to?
