Thirds & Fourths Positioning

Precise window positioning in thirds and fourths of screen space

Overview

Thirds and fourths provide more granular window positioning than halves, enabling precise layouts for multi-window workflows. These actions divide the screen into thirds (33.33%) or fourths (25%) along horizontal or vertical axes.

Horizontal Thirds

Defined in the static horizontalThirds array (line 78):

static var horizontalThirds: [WindowDirection] { 
    [.rightThird, .rightTwoThirds, .horizontalCenterThird, 
     .leftTwoThirds, .leftThird] 
}
