The control center starts getting real cluttered very fast when you have 10 or more VMs, which I do. This is more likely the case for developers (whom the pro version is marketed towards). We need a way to organize the VMs. This could be folders or a filter. I would prefer folders, but would settle for a filter if you also add tagging. For example, I could tag all my "Browser testing" VMs and select that as a filter to show only those VMs.
