I'm addicted to using the X, Y, W, and H parameters in the upper right of the window in Illustrator . It makes precision layouts, resizes, and measurements trivially easy.
I understand you can get precision placement in Photoshop by putting a horizontal and vertical guide exactly where you want an object to snap to, but there are countless disadvantages to that method. Are the writable XYWH fields hidden somewhere in Photoshop as well? Or is there another way to put something at an exact spot, resize it to an exact size, or read off its exact dimensions as easily?
