My clients are complaining that when they enlarge the page view in Adobe Preview, they can't see half the page and don't see a way to scroll to it. The problem is the slider at the bottom of the browser window doesn't appear until you hover over it with the cursor - and once you do, it is very shallow and hard to click on, especially for older clients with less than perfect vision.
Could this not be made visible once the view is enlarged, and make it a bit thicker so less nimble hands can click on it?
