I understand what you're saying, but I don't understand why you're saying it
! while it's true that most eInk reader are 6" screens, I would guess they make up a mere plurality of all devices used to read ebooks. And moreover, people change font sizes and font-family on their eInk readers, so what you're looking at on your 6" is more than likely NOT exactly what a reader will see on his or her machine. Checking to see if your book "looks good" within certain fixed, precise dimensions is fooling yourself into thinking that more than 1 out of ten readers will see it displayed exactly as you've designed it. Given that, why not just satisfy yourself with the ballpark capabilities built into Sigil?
