In my setup, the largest external display is Primary, and that's where I do most of my work. The other two external monitors are smaller, and far enough away that I can't use them for viewing text. However, when I open a new Finder window (e.g. cmd-N), it often opens on one of the non-Primary displays, which means I need to drag it to the Primary.
What is the algorithm used by the Finder to decide where new windows are placed? I would like to specify that all new Finder windows should open on the Primary display.
