/* Class = "IBUIButton"; normalTitle = "Other"; ObjectID = "21"; */
"21.normalTitle" = "Alternative";

"Other" could be "Andere" or "Sonstige" as well if "Alternative" is
really too long. Both alternatives (sic!) are not as elegant as
"Alternative", though.
If you're a native German speaker, please don't even *think* about using
"alternativ" - it's not a noun and would be horrible here.

/* Class = "IBUILabel"; text = "Paragraph spacing"; ObjectID = "72"; */
"72.text" = "Absatzabstand";

Not 100% sure about "Absatzabstand"; it's logical and makes sense to me
but there might possible a better fitting German professional term for
it. If *you* know it, let *me* know.

/* Class = "IBUILabel"; text = "Page turn style:"; ObjectID = "199"; */
"199.text" = "Umblättern";

Ok, ok, "Umblättern" *is* a bit clumsy but how would *you* call it?
"Blätter-Stil" - disgusting. "Seitenwechsel-Stil" - too stilted.
Originally, I wanted to use "Umblätter-Animation" but that was worse, I
think.
