It would be very useful to have interaction between the control panel and the map.
i.e.
If I highlight a mark in the control panel, I would like it to flash on the map.
If I highlight a mark on the map, I would like to be 'thrown to it' in the control panel, (if the panel is open).
(The existing behaviours of markers on the map, (flashing; turning white; suppressing other headings, etc.), are great and should be retained.)
