Well, Purple Lady, your reading preferences are entirely different from mine, anyway.
I just couldn't possibly read books that are not full-justified -- just can't stand those straggling line-ends on the right side. So, I'm unable to comment on your screenshots, because I wouldn't be reading books that way in any case.
I think "2" is really too large a first-line indent -- it's strange that it's Moon's default. "3" is quite absurd. "1" suits me perfectly in all books I've read in Moon so far. No first-line indent is unacceptable to me. (That's actually a standard for many German publishing houses, and it frustrates me a lot.)
Interesting that Moon+ gives you those "1, 2, 3, off" options for first-line indents, whereas for other layout features, you get the option to increase/decrease margins gradually with button presses, with exact numeric values being shown. Well, I'm not gonna complain about that -- that first-line indent "1" is exactly what I was missing in Moon+!
