In exo v1, I used to make an intensive use of the DisplayContent portlet to write the articles from my company web site.
It was really convenient, because with this portlet I was invited to use te wysiwyg editor to write down the page article, then switch locale and translate it and everything was stroed in the JCR and my page was available to my english and spanish customer.
With v2.x, I can't find a way to do the same thing. I've tried to use ecm portlets but I can't find a way to reproduce the DisplayContent behavior from v1.
