Brake Bros have use cases occasionally to reopen an archived project to make a minor change which means they have to save it back live, make the change and the re-archive.
Use case would be say they submit a project but don't get confirmation say on a Friday that the AM has submitted it if it's by email. They need to go back and then change the completed day to say Monday as that's the date it closed. They have to unarachive it, then resave it, make the change and then go back and archive. Would be great to be able to make minor tweaks while remaining in archived state.
