Filtering (out) the meta categories would be nice (so you can look at just the meta categories or just the countries).

Something that I don't think is available at the source that would be a nice addition would be a per capita (looking at the population and using it as a basic sortable column for quick reference).

It's a very cool tool and resource, though.

I would love feedback on my site. The goal is to help share open source data through a simple UI.
