Describe your idea

It would be good to be able to archive things in Aha. we were trying to streamline our initiatives and there's old ones in there that have been marked as achieved. you can filter them out in some places, but like when you're assigning an idea to an initiative it still comes up in the list and just kind of gets in the way. so it would be good if there was some way to move it as it's not relevant but not delete it as want the record of it.
