Modification for immersion

[Dönitz78]

Hi,

I want to modify some for immersion but I can't find how, if someone can help me. 3 differents point :

1/ Torpedoes

I want to be able to calculate myself the time a torpedo takes before impact, so I would like to remove this:



But also on the stopwatch no longer see the red indicator which indicates the time before impact.

2/Fuel, Co2, air pressure


In menu here :


I want know if it's possible hide this 3 indicator in this menu, i know with "option file editor" we can hide this indicator in game, but in this menu i don't know where i can hide this


3/Navigation map


And the last point the Navigation map.
I want know if it's possible delete all acces at the navigational map, obligation go in the submarine and click on the map for have access, so for keyboard it's ok, but for this i would like know if it's possible delete this or hide :



Thanks for reading me, and sorry for my english. I hope have solution.
