We are using JIRA and confluence, with the comala boards app, at work.
I'm trying to set up a simplified tasks list, without going full agile/kanban.
We would be using this board for a sustained period of time (year+) but it looks like if I set it up to hide 'completed' tasks, it deletes them?
We would like to be able to go back in our annual retrospective and check tasks completed, so deleting them isn't ideal.
Apologies if this is a stupid question - this is my first foray into confluence, comala, JIRA.
