How does the Phase Doctor work?

My response in the Phase Alignment request thread:

I use parallel paths very seldom but I did try the Phase Doctor and it works really well.

Some people may expect a straight 0° - 360° phase shift parameter, but it’s not set up like that. Phase Doctor lets you choose if you want to flip one side or the other by 180°, then gives you the option to include additional shift. That’s my best understanding of it, anyway.

I don’t have an official description for that, though.
