Why does the scroll indicator disappear in the page scroll bar, when reading a pdf in adobe? See the attached screen shot. The scroll bar doesn't show the location you are in the document until you hover over the scroll bar with your mouse, which is really stupid. Why can't the page scroll indicator continue to show all the time? Not only does the indicator help you know where you are in the document, as looking at the page numbers is more cumbersome and not easy for this purpose. But the main issue is when you want to move the page using the scroll bar indicator, and when it isn't showing you have to first hover over the scroll bar to make the indicator show up ( which is really annoying) and then you can click and hold the indicator to move the pages up or down. This extra step in having to find the indicator is totally unnecessary and a time waster when the indicator doesn't take up any space that needs to be used for other things! Please just make the page scroll indicator show up all the time!
