When sticky edges are enabled in a vertically tiled layout, the cursor does not
see any resistance at the border between the two screens. This feature would
possibly be more useful than the sticky edge for horizontally tiled layouts, as
it would enable the user to quickly access the menus and window buttons of a
window at the lower screen.

Attached screenshot shows my currently configured layout.
