Enabling which patch(es) gets me the most text in the top and bottom areas when reading? In other words, I want to have text go as high up and as low down of the screen, so that text will be almost "kissing" the black plastic frame.
In libnickel.so, there's
-- ePub fixed top/bottom margin
-- ePub disabled built-in body padding bottom
Another question. in the same file (libnickel.so), there's a pathc called "Force user line spacing in ePubs (part 1 of 2)". The description says that enabling it will "spoil the formatting in some books".
What formatting will be spoiled? And what books will be affected?
