Query 2.7.8, Quint Iteration 7, QuInt 8 08/28/15, Quint 9 09/18/15
It would be useful to be able to get stats from individual indexes about how often they are used. You can see whether a specific query uses certain indexes using explain() but this would allow you to easily see if the index is being used at all. It could just be a simple incrementing counter every time the index gets used.
