Not a huge deal but the "Go to A Scope" and "Go to PPI Scope" are reversed, when click go to PPI it takes to A scope and when hit Go to A Scope, sends to PPI scope. Just noting to future versions so can be corrected
Idea...perhaps a mod could be made to blank out the PPI scope for early war since PPI scope did not come around in subs until SJ-1 in late 43/early 1944
