Hi,
Being interested mainly to know which planes are passing over my head (but in my case they are few with around half hour intervals in between them), I would like to be able to trace a circle around my (or any position why not) and when a plane enters this circle an alarm would ring !
Simpliest way to do it would be to center the wanted position on Windows screen, set zoom and be asked a Km/Miles range.
Would be nice to implement this feature !
