"""Tiling layout that works nice on vertically mounted monitors
The available height gets divided by the number of panes, if no pane is
maximized. If one pane has been maximized, the available height gets split
in master and secondary area. The maximized pane (master pane) gets the
full height of the master area and the other panes (secondary panes) share
the remaining space. The master area (at default 75%) can grow and shrink
via keybindings.
