I'm looking to archive tasks which ended up being dead ends/put into purgatory and want to keep them off my kanban to keep things clean.
I do not use sprints/epics/backlogs on the board and due to how the boards are designed, the right-most column will always be the official "done" one, so I can't even de-clutter by putting the things that aren't to have attention paid to them off to the side and out of the middle of the board.
What options exist in this case? Are any of them free/don't require any kind of admin/security review (built in, not plugin) or a paywall?
