Very cool :) Feature request: can the thickness be a function of the number of pages?

It has been suggested before, it’s a very good idea :)

Well each page is 100mic roughly for 80gsm paper which is pretty standard. So if you did something like a 200 page book that is 20mm's which at 72 dpi roughly 54px's or roughly 27px's for a 100 page book.

That's excluding any cover page, which heavily depends on binding/hard cover/what ever else.
