Yes, this is true, lately we have not really "new mods"...sh3 is showing it's age and how we, this community, worked on it so much all this past time.
About the flags, IMO, this emission propertie (what I didn't knew about until now) really makes the trick on the above matter (very difficult/impossible identification at night into the game), "emulating" at a better degree others ways that real kaleuns had at their disposition at that time (radio interception, ships unique detail, etc), that we can't add to the game (until now). The idea behind this is that is better (again IMO) to use real magnifications&dark environments at night as a realism option than make them unrealistic (wrong magnifications or enlighten nights). It's good to have choices.
