Suggesion for a more compact grid 

I'd like to propose a new grid format for the income inequality list. I've uploaded a screenshot here. By combining the UN/CIA "R/P 10%" columns and the World Bank/CIA/GPI "Gini index" columns, and by writing the years directly besides the values, we can make this grid much more readable. Of course, one could not sort by year anymore, but I don't think this is such an issue. Whichever source (UN, CIA, WB, GPI) has the latest value, that source's data should be displayed. I don't see a need for displaying different sources, since they probably all calculate those indices using the same data. I'll leave some time for people to comment on my proposal, and if no one minds, I'll go ahead and implement it.
