Google Squared

Google Squared is an interface for structured data on the web (like Wagn!). For an example, see http://www.google.com/squared/search?q=endangered%20animals&suggest=4 , and for a blank square see http://www.google.com/squared/table/ . Last night I thought up an interface for creating and searching structured data in Wagn, and then I remembered Google Squared -- and it's almost exactly what I imagined. I would add a search box above each column that filtered results as I typed and could stack filters. I imagine that a Wagn interface similar to the GS interface could be done with the first column as a card and all other columns as plus cards. It'd be so great! Maybe I'll try to make it work in Wagn... maybe I'd have to learn CSS first...
