Ahh... that would be those little icons in the Menu folder... I would have to dig through my "documentations"... which are an absolute mess... probably lost to posterior - er, posterity :O: - perhaps someone else remembers which one(s) you need to re-enable... Most times, if you get a report, just make an "X" where they report it, and draw a rough line for direction. I will sometimes, if there is not too much going on, and I haven't gotten lazy about it, I will use the compass and draw a small circle around my mark, so it is visible at small zoom levels.

Thank you for your insights. Also maybe you know how to make that you could detect aircraft a bit further?

Why - radar, of course... :har:

but seriously, I cannot remember for certain, whether the sensors.cfg or the sim.cfg in the Data / Cfg folder does the most... but there is a "balance" there that can be difficult to achieve. You might be able to make night surface attacks possible, but will the ships shoot at each other before 2400 yards? Will your crew shoot at airplanes before the bomb hits? That sort of thing. If you increase the AI Visual, it affects enemy as well as friendly forces... that of course, can also affect your torpedo targeting distance as well...
