Unfortunately this is missing all the fixes that Izgud made for the Ahnenerbe gui!
It has doubled TDC dial labels in the attack map, which he
had fixed.
Crew talks when using pgup or pgdn to adjust periscope, which he
had fixed.
It lacks the added RPM chart at the hydrophone station.
I haven't checked the RAOBF mark (which was wrong in Ahnenerbe), but I suspect it will be wrong here too.
I also notice that there are two sets of reticles inside the UZO, and that the scale of the reticles in the Obs scope and Attack scope are wildly different.
