The new maps in Piwik 1.11.1 are great :-)
There are two small things to improve if you have only little numbers of visitors because
a) you are running a small website
b) you select a short time period
1) prevent the disappearance of visitors if you switch from regions
(attachment 1) to cities (attachment 2)
2) it would be very interesting to the show on mouse hover the names of the other cities if they were condensed (attachment 3)
Thanks for the ticket. I reduce the scope to: "Map of visitor cities: show other cities names in tooltip when clustered"
+1 This is something I also find pretty annoying.
