I'd like a zoom/scroll bar.

The entire length of the bar is the entire length of the sample, the scroll portion is how much of it is displayed.

You move if left, the interface scrolls left, and so on for right.

BUT, if you attempt to scroll up on this horizontal scroll bar, It magically zooms in, and also zooms out when you try to scroll down.

This also removes the need for scroll buttons.

I'm also not satisfied with the quantity of Zoom strengths there are. We need more increments IMO.

Thanks
