I am noticing what I think it's a big gap in terms of turnover and job changes. Even though you can add workflows to a Collection for development and update purposes. Only the original owner/publisher can see the version history for a workflow. At least that appears to be the case in 2020.1
Is there any discussion for the road map to include a way to transfer the ownership of a workflow from one user to another? this would alleviate the need to publish a brand new version and then reset all the scheduling.
