Problem description:
As I currently use wekan, my "done" tab grows quite large.
I don't wan't to archive the cards because they keep valuable information that I sometimes need in a later point in time (e.g. to confirm someting). As the seach comes available (hopefully ;-) ), it is even more useful to be able to search through those tasks.
What I'd propose is something like a filter that allows for hiding tasks that have been in a column (done) for longer than n days.
