# We use this along with
# /a/opt/i3-alternating-layout/alternating_layouts.py to anticipate when
# 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
