Feature request: Lock page slider (on long) books

[gojzdar]

Problem:
When reading, I sometimes accidentally swipe the screen the wrong way and I change the current page thought the page slider (slider on the bottom that shows the current page). This is especially annoying with 1000+ page books, where a slight miss click causes you to jump a few hundred pages.

Solution:
1:
Add an option to lock the slider, requiring you to hold it down for a (literal) second before dragging it.

2:
Add an option to get rid of the slider entirely. I don't really see the use in it.
