- good map experience: smooth of zooming in&out with delicate icons or buttons' transform; the density of pins on map is appropriate(can hardly causeTrypophobia) ;
- good search experience: the (multiple) selected search criteria can be easily seen and cleared;
I quite like the way Compass have handled search. I think it fits your second criteria:
Thanks Duncan. It lists out search criteria from "more filters" which can be multiple selected as tags with keyword as a tag in search bar, which is clear.
