> When having multiple instances of an app, the doc adds a "dot" by the app icon. That's simply not the case. The dock adds a dot to the application icon if the application is running. If you have multiple instance of the application running, there will be multiple icons (each with a dot) in the dock. This is fairly difficult to do, the only way I know how is by starting the application again from the command line. Well, or when you're running an application you are developing from Xcode. So not 100% sure what you mean with "multiple instances", but almost certainly not actual multiple instances. I am guessing you mean an application with multiple documents open. So basically, what you regard as "bad UX" is simply you trying to map assumptions from one environment onto a different environment, and finding that your assumptions don't reflect reality. And yes, the application will be running (showing a dot) whenever you have 1 or more documents open in the app. To switch between documents of an application, you can either go to the application's "Window" menu and chose one from there, or to the dock icon and choose one from there.
