Works with DockDoor

By Ighor July, on the Mac App Store

Parall runs multiple independent instances of the same Mac app, each with its own name and Dock icon and, where the app allows it, its own accounts, profiles and data. It can also turn websites into apps in your Dock.

With DockDoor: apps opened through Parall are recognized, so hovering an instance in the Dock shows only that instance's windows. This works in DockDoor and DockDoor Pro.
