When Thord and I was poking around the app today we got an idea that might be possible.
We would like to keep the current map tab and add three more tabs with maps:
Non-aggregated symbols on all ringing spots in the selected dataset.
Non-aggregated symbols on all recovery spots in the selected dataset.
The two maps combined, with ringing and recovery for each bird connected with a line.
Show recoveries using lines on the map
