It’s beautiful, and very fast.
A few suggestions:
-centre the map on the current location (as you said), but make the zoom level much closer – otherwise all I can see is a sea of blue and red!
-map caching (so it doesn’t need to reload each panel each time I open it)
-dock caching (so it will show the location of the docks, even when I am underground/out of network – dock location is often more important than dock status)
-please please turn this into an iPhone app with a sexy icon (Yell) – I’d pay!
