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