Everyone on our team would benefit from having access to each other's workflows -- including workflow results and scheduling -- but publishing them to gallery where any user in the company can run it/ download it would present a security issue. Functionality that is not met with Collections. I found a similar idea, but not anything that encompasses the whole thing.
It would be of immense value to have a Team Gallery - something intermediate to the company gallery and the private collection. This would enable our team to have access to modify, publish, schedule workflows as a team.
