Hey, that's a cool feature! Thanks a lot! I didn't know that up to now,
but anyway: How does this automatical white balance work?
    

I don't know how exactly this engine ticks, but I can to to guess: it
searches for the lightest pixel in the image and makes GIMP believe
that it is white and then it shifts other colors appropriately. But
that's my guess. Probably gimp-help package contains information you
want to know.
No the official gimp documentation on the homepage doesn't contain anything about it. You can verify it here: http://docs.gimp.org/en/ch09s07s11.html
It doesn't even appear in the screenshot of the menu.
Your idea how the automatical white balance works sounds good. IMHO the automatical white balance on a digital camera should work the same way, shouldn't it?

Some info on Levels dialog ("Werte" im Deutschen, soweit ich das
verstehe) is here: http://docs.gimp.org/de/ch06s05s06.html
Yes, that's correct. Thanks!

Cheers,

Timo
