Periscope solution view.
 

I could not think of any other way of describing it, but basically I have RFB1.52 and Operation Monsun installed, and now it shows a notepad to the right of the periscope that shows angle and speed, I preferred the original one that showed a nice diagram of a ship with angle off bow etc.

Is there anyway to use the standard solution thingy rather than the notepad, or is it just something that is the German subs?

That's German sub specific. And if you are a manual targeting user than the German setup will have you pulling your hair out.
