When you have multiple displays and want to move your photoshop to the other display its very frustrating that EVERY window pop-up has its own position stored. This means that brightness/contrast, filters, save as, curves, etc etc etc has a position stored since last time you positioned it. So, if you want to move Photoshop to a second monitor you need to re-position every window that appear until you have done it to all of them. Once you decide to switch to the other monitor again the whole process starts over.
Especially problematic if you have 2 screens with different resolutions, because some times the windows are gone, unless you mirror display and find them and then reposition them. There should be a command in Photoshop were you arrange ALL windows and every pop-up to the current display and default center screen position for convenience. This applies to both Windows and Mac version of Photoshop..it has bugged me for years.
