If you get server up and running and develop 200 workflows and then schedule them, and then want to change the schedule on one of them, it is a total hassle. What did I call that workflow? you sit there wondering as you look through a huge list of workflows.
It would help a lot to have the concept of projects / folders / some type of logical grouping so I say, What did I call that workflow? while only looking in the public safety, or HR, or Accounting, or whatever subset of workflows. I mean, we don't have to go all crazy and have collections, districts, and private studios, but at least one layer of categorization would go a long way in making a proliferation of workflows more manageable.
