Navigation mods

[B.N.R.T.]

Welcome, everyone, to my first post in this magnificent U-boat simulator forum.

I've got a quick question regarding mods. I'm no computerexpert, so you may have to go slow and easy on me when explaining things.

Anyhoo, I just completed my first patrol (using GWX) with a nice tonnage of about 25000 and I want to make some realism/immersion changes for my next patrol.

Specifically I want to:

1) Get rid of the circle/bearing tool telling me where my sub is.

2) Get rid of the course plotting tool and the erase all tool in the Navigation map.

Is this possible? Will I get a quick answer so I can start making the seas unsafe sooner? Will I get lost when I don't know where I am?

Thanks you in advance,

Geert

EDIT: And another question. How are contact reports 'made'? The little ship (or convoy, which I haven't seen yet) icons that sometimes appear on the map. Are they generated only within a certain radius of my U-boat? Because I've only seen them near me, I think that is the case.
