There are some issues with the paging arrows in the bottom left. One thing is just a little confusing at first. You are doing something that is not typical UI. I've never seen software that lets you scroll, and also tells you which lines are being displayed in just the viewable window, and also lets you page through the scrollable view. Once I figured out what was going on, it is actually pretty cool. But then I found that if I change the window size, then use those paging arrows, they don't give me correct results. They seem to skip large amounts of records. I would suggest first, of course, to fix that errant behaviour. And then maybe add the word 'Viewing' before the range of rows displayed, or something to make it clear the user can either scroll to see more records, or use the arrows to jump scroll.
