Kindle doesn't support this, but you said ignore it.
..I thought about it, and honestly I can't. This whole styling of books is much ado about nothing
What I want from any e-reader is good contrast, long battery and ability to change font size (sometimes my eyes get tired (I have astigmatism), so I go for bigger fonts).
As for the style, I do like nicely done headings or a stylized first letter of the chapter, but that's about it.
I guess what I'm trying to say is I prefer the e-ink to any other reading option even if it includes stylized books.
