I run OSX with tons and tons of application instances; so I am looking for a way to tell OSX to stack application instances in the dock the same way Windows 7 does. (blasphemy, I know) Is there a way to do this?

How do you get application instances - the standard Apple way is for one application to deal with many documrnts – Mark Jun 29 '12 at 22:57
Eg. My dock is full of finder and firefox instances. – Colin Jul 1 '12 at 21:17
How do you start them as both those give me only one instance if I start them from dock or finder – Mark Jul 1 '12 at 23:45
LOL, the possibility that the invocation path matters hadn't occurred to me. I see, well if you want the additional windows (at least when using Firefox) you can request a new window via Firefox's file menu. – Colin Jul 2 '12 at 20:06
But a new window does not open another app instance – Mark Jul 2 '12 at 21:42

Have you tried HyperDock ( It adds several of Windows 7's task bar features to the OSX Dock, and as a wonderful bonus also enables window snapping (like Aero Snap).
