In Windows i can open a new instance of an app that is already running by holding shift and clicking the app in the "dock". On MacOS i'd have to open the terminal and run "open -n path_to_the_app". Is it possible to fix that somehow so i can use the shift-key to open a new instance of an already open app?
You can also open an application by name with
If you use Alfred, you can create an action for opening a new instance.
