I started using GH KanBan RapidBoard and it's awesome.
However, I can see now in my "Done" column all my past issues that were done.
As this is an OPS project and KanBan board, I do not have really "sprints", "releases" or anything like that. So, how to limit the number of issues displayed in the Done column to some reasonable value? (like, this week solved issues or sth)?
