  24 # There are only 2 cases where I want single window split containers.
  25 #
  26 # * just before creating a new window in it.
  27 #
  28 # * When I want to make 1 window a split container and bring an existing
  29 # window into it. In vanilla i3, this is super awkward. Usually, you are
  30 # starting out focused on the window you want to move into the
  31 # container. So, you focus the window which is to become a container,
  32 # split it, focus the window you want to join the container, move it
  33 # into that container. 4 actions, totally annoying. Lets simplify this
  34 # to 2 actions, a key to say what split we want, then a key to say which
  35 # direction to move the current window. Since we have a hook that erases
  36 # all single window split containers on focus change, we can consider a
  37 # single window split container to indicate the split we want.
