In several of our Kanban boards, the "Done" column has become excessively long. So much so that scrolling through the page takes a bit of time. We need all of those items there so that we can search and find info. pertaining to those completed tasks. Is there any way to truncate the cards so that they take up less space? Has anyone found a way to manage a really long "Done"column while still having the tasks available and searchable?
