It would be cool if on hover of a corpus filter, you could see the number of passing tests/total tests for that filter, including the all corpora button. Right now, interpreting the percentages below is slightly complicated.

Interface idea: button partially filled by percent passing tests

[Zachary-Kelly]

also for the CLI, number for each corpus row and a summary at the end
