I am very please with the basic Radar so far. The fact that it is actually simulating a Radar system makes it a very valuable tool and the options available are already decent. The chart is basically useless at the moment but that has been mentioned before. Here are some wishes for improvement.
Radar Wishlist:
The scanning animation is very rough refreshing only every 20-30° at once. A smooth scanning animation would be more convincing.
Day and night color scheme
Compass rose
echo trails
Courser with bearing and range
Hoping for an advanced Radar (with ecdis integration) in the future
Chart Wishlist:
Ship symbol fitting ship outline
Day and night color scheme
Course/Heading indicator with a vector
Full zoom range
VRM/EBL options
Course/North up options
Navigational aids visible
Autopilot course indicator
Basic route with waypoints (optimal with track pilot integration)
NMEA output! (to offload development efforts towards more sophisticated external solutions)
Hoping for an advanced ecdis in the future
Virtually everything raised here is basically already part of the big brother Nautis.
