+xinerama monitors xorder
+========================
+
+Description
+-----------
+Sorts Xinerama monitors by their `x_org` value (horizontal position),
+ensuring directional monitor movement (e.g. `Mod+Shift+Left/Right`) reflects
+physical screen layout from left to right.
+
+This is helpful in multi-monitor setups where the logical screen order from
+Xinerama doesn't match the physical layout.
