Hi!
I've been playing SH3 for some time, and now I'm trying SH4. There are some things that annoy me, because they are done worse than in SH3:
1. No salvo mode - tho historically accurate, so I won't complain.
2. Why aren't the torpedo courses drawn on the attack map? Do I need to click some option manually or what? I'm using the auto targeting.
3. Is there no auto recognition manual like in SH3? Do I really need to click through the entire manual to get the keel depth?
4. When I use metric system, are all the gauges also metric?
5. Is there no time/roadmap for subs/upgrades like in SH3?
6. Is there any gun actually utilizing the AA ammo? As the Flaks seem to utilize AP and HE ammo. Looking through the CFG files I noticed a 5" deck gun AA ammo. Does it mean, that my deck gun crew will shoot at planes?

What sub/year combo allows this gun?
