hi everyone!
looking for an simple mod to disable symbol/range ring of my sub from the nav map. Been using manual targeting (no map updates) using the wiz wheels

I build (KM and USN) for longer now and want to try "full" manual targeting . I think my computer won't handle OLC, so is there a mod that removes the sub icon only? Preferably only in the higher zoom levels, definitely not willing to go sextant
would it be possible to let the icon show up speed 0? This way you could still plot when at full stop, which seems realistic to me. Or I use MoBo for this, or use an imaginary sub position and plot on the normal nav map.
