It would be handy to filter after query with query_filters not only categorical values (e.g. US/EU etc) but also floats. Today the system allows it but actually it becomes an endless pull down select box (e.g. 0.1244, 0.1234, 0.1535 etc). If the underlying data is float (aka continuous) a slider filter could be nice.
Ditto for Query Parameters! This would be a useful interface for either one.
