My team is trying to move from Sprint board into Kanban board. While working in Sprint board, we worked with subtasks to break down the story into smaller pieces. Now after changing our board into Kanban, we noticed these subtasks are also listed in the Backlog. This is really annoying as it clutters the roadmap. On top of that, since the parent story can have different status compared to its subtasks, it makes the roadmap looked even worse. If I exclude the subtasks using the filter, the Backlog will look fine, but then I will lose the subtasks in the Kanban board. How can I achieve a middle ground where I want to see the subtasks in the Kanban board but hide them in the Backlog?
TLDR: Work with Kanban board. How to have subtasks in Kanban board but hide them in the Backlog?
Thanks!
