Max and min indexes with page snapping

[nt4f04uNd]

Allow to set index bounds of how far user can scroll in both directions. This will allow to have content always filling all the screen. Example with in my case - I have a list of pages, but I would like user not to go that far so the empty space appears.

I would like to always see

But I also can scroll to first and last index so that doesn't look good
