Is there any way to get rid of that sign that pops up when your guys spot an enemy contact (The one that says "Dive to periscope depth" "Continue with orders"..etc...) ?
For realism sake, I would rather just hear the warning and react myself. I almost didn't notice the sign there because I was in a darkened area of the boat and the sign is transparent and I got hull damage and almost lost my boat while I was clicking around and nothing was responding.
