I understand the idea, however, there is either no flexibility or it is not working properly. For example, adding widgets to an extended footer - I am unable to place them side by side, no matter how I adjust the widget's position. The widgets line up in a straight verticle line, rather than a horizontal line, as permitted by the theme.

And, since this is an experiment, why disable the previous method of placing widgets!? Seems it would be nice to have the option until the experiment is working properly.
