In response to the first question this is from the Hitman GUI manual:

XII. Slide-out wiz wheel for enemy course and AOB

The Lagewinkelscheibe (AOB plate) added is a copy on a real one, and its functions are more simplified and easy to use than the previous one incorporated in the U-Jagd tools. To make it appear, hover your mouse near the right edge of the screen, and it will slide out.

It will only work when the TDC is locked, and any of your optics trained at your target. The Uboat or ownship course is at the top, and the pointer will always show true bearings (i.e. relative to North, not to your Uboat’s bow).

To use the wiz wheel the only thing you have to do is pick the white centre wheel, which represents the target and:

A) Turn it so that the AOB is set opposite the mark “Lage” in the pointer.
Once done, you can read the target’s course in the outer black wheel.

Or

B) Turn it so that the enemy course is set at the external black wheel. Once done, you can read the target’s AOB opposite the mark “Lage” in the pointer.

It's a really simple and useful tool which I always like to use. Once I've ascertained a target's course I can just use this to calculate the AOB soon before firing. Easy. Nice that you can use it also in reverse and get course from AOB.
