Can my sub NOT "Return to Course"?

[sargexmy]

Sup peeps,

so basically, i plotted a course out of Kiel on my first own patrol. Then i accidentally pressed the rudder button so my sub now is turning slightly right.

First of all, i CANNOT find a rudder diagram to show the status of my rudders!
And i dont want to stop my boat, delete every way point and re-plot, so I looked for the "return to course" button that was under the Navigation screen/panel in previous SHs. I CANNOT find it!!!!! the manual is useless...
and going to my navigator, I can only tell him "keep up the good work" while he can't even order a return to course!

useless crew, so i ran the sub aground and ended everyone's carrier early...

so anyone know how i can "return to course" w/o re-issueing all my navigation way points? and anyone feel that the navigation tools are so limited? like how do u scroll the map quickly while the plotting tool is currently active so u can plot way points in areas far away from the sub, but still zoomed in. I can only use the damn up/down/left/right buttons, and that is just too slow.
Imaging trying to plot way points to navigate a canal: you want to be zoomed in to plot precisely, but there is no way u can keep ur sub in ur screen to click it to select the plotting tool w/o going back to where ur sub is! and then u have to scroll sloooowly back to where ur last plotted waypoint is. that is just painful...

much help and tips appreciated
