In HubSpot inbox one can add a ‘category’ to the conversation which in turn adds said category to the ticket created from the conversation.
Some categories might not be required after some time but if they have been used, they cannot be deleted. Removing the category from all relevant tickets is not a solution as you would not want to loose the data. Therefore, being able to archive categories that are no longer needed would be great! This in turn would mean they would not come up as an option when selecting a category for a conversation/ticket but still visible when viewing past converstations, tickets, reports etc.
