Just one more idea - with that kind of feature we maybe could use radars for counting asteroids nearby ship in space, and then use that e.g. for determing speed of the ship.

I personally feel that having a radar be a circuit network signal source as opposed to just a propagator (since universe mode allows it to technically emit a signal, but it is not the source of that signal, it merely passes it along.) is not what I would like. I would rather have a separate ...

Actually i think we do not need this kind of alert. Instead it should be replaced with radar being able to track how many bitters/spitters/spawners&worms does it detect.

From that then we could build circuits for any alert we need - e.g. larger increase in spawners/worms - means we have detected ...
