Coverage remained the same at 97.5% when pulling db671bd on tupy:patch-1 into 584e52b on pheuter:master.

Hm, what would be an example of when one would use state.query to fetch data over state.params?

[tupy]

For instance, a feed of documents that it's possible to filter/sort using a query param:

/feed/new-feed-1?filter=tag1&sort=date

The react-router receive these params and fetchData() should send them to load the correct data.
