Visual indicator that a date has data in the filter widget calendar

[BeLockwood]

I think it would be really helpful to have a visual indicator that shows dates in a calendar that have data. Something like a little blue dot centered in the date box or maybe the whole box filled in with a  faded color. You could drive it using a date field from the same layer that drives the filters.
