I want to read prepubs on my kindle!
I can really use a prepub download button. It's not like that you cannot already copy paste all the html text right from the page but that's kind of a hassle.
And yeah I can read it on kindle experimental browser but it's terribly clumsy.
My rule is books are meant to be read on paper or at least e-ink not on a monitors. I already stare into them all my day at work.
