+# We use this along with

+# we want to split/tab windows. There are 2 options of when to do it:
+# just after a window is created, or just before a window is
+# created. Doing it after a window is created allows you to move a
+# window into the split that only has 1 window, whereas the other way
+# doesn't. For my use cases, I think I don't really want to move it into
+# the split if it is a tabbed split.
+#
+# I have a keybind which disables both, it runs /b/ds/i3-auto-layout-toggle
