Set default container layout for i3 window manager

I am using the i3 window manager for a few days now and I am amazed how well everything works. :)

The only thing I am still looking for is how to change the default container layout to tabbed/stacked.

I found a post in a forum from 2010 where somebody states, that this was not possible back then.

Does anybody know, if there is a way to accomplish changing the default container layout now, or if is still not possible?

possible for now :) in .i3/config add line

workspace_layout <default|stacking|tabbed>

eg. workspace_layout tabbed for windows open in tabbed mode in workspaces

from http://i3wm.org/docs/userguide.html#_layout_mode_for_new_containers
