if you go to the forum post on the Latikai client it will explain how to get it running....
stupid Java security BS makes it a pain to get set up.
all the icons should by default be shown... but there is an option in the client options to turn them ALL on/off.
and if you go to the radar file you can fine tune what ones you want to see and what ones you do not wish to see.
i can help with the majority of radar file questions you have.
