I have a chess book in pdf with 14 pages of introduction and preface.
So page 1 starts actually at page 15 (14+1).
If I go to 'go to' I always have to add 14 to go to the right page number.
What exactly is the option 'First page offset' in the book setting meant for?
I was thinking this problem could be solved with this option but it is not, maybe it would if I could enter a negative value like -14 but I can't type a - in the box on my android galaxy tab A 2018
Maybe I can just remove the first 14 pages from the pdf book?
