I have a Kanban board going, but the backlog is large enough to be unmanageable. I'd like to have a pair of queues before the backlog, "untriaged" and "triaged", where the bulk of the long-range roadmap tasks will sit, instead of cluttering up the daily-use version of the kanban board. Having these two extra priority queues will also keep a clear distinction between tasks that the team can freely adopt (stuff in the backlog) and stuff they can't (triaged/untriaged.)
I looked at filtering the kanban based upon priority, which would remove untriaged tasks, but it wouldn't allow me a space where I can roughly sort these tasks by priority.
I'd welcome any answers that accomplish the basic requirement, though I don't want to have extra columns on the Kanban board. Jira wastes too much screen space as it is (I would love to jettison it in favor of Pivotal).
