Added through a setting vimlike_scrolling which is turned off by default
A hard-coded (for now) cushion of 5 lines that allows for previewing the next lines while scrolling
A separate struct ScrollState with getters and setters for the current_focus field to disallow setting the field without updating the last_focus field

Wow… thanks for pr. I’ll review soon.

An initial cushion value is now set to 5. The cushion value is now dynamically set to accommodate small view ports (table heights).

I wanted to avoid mutable state in UI code, but looks like it's worth the tradeoff.
