Mini Calendar Exposed Filter

This is a feature request and I think it's still valid.

what's wrong with the current date picker?

My client is looking more for something like in #7
A mini date calendar that highlights or links dates that have results and when you click the link you get the results like this: https://www.optum.com/en/care/locations/optum-california/events.html

That is different from the date picker that shows a normal date field and has no feedback on which dates have results, you also have to click the field to see the date picker.
