Crewmembers can be archived to hide them from the list of crewmembers in order to declutter the list if they are no longer used if desired. This does not remove them from any entries, it just hides them. Crewmembers can be archived by selecting the Archived switch to on in the crew details section, or by swiping left in the crewmembers list. Archived items can be viewed by going to Settings/to Settings > General and turning on "Show Archived Data".
