Please add ability to Group Flows.
While sub-flows are a great feature that I use frequently to break down the various tasks in a particular flow, I need the ability to group flows either based on our process hierarchy definitions or flows from different departments, etc. Would be great if this is implemented in the form of tabs, like my browser tabs.
