Add a scrollbar to quickly scroll through saved pages/bookmarks

Can we please have a scrollbar to scroll through saved pages/bookmarks? I save a lot of pages to visit them later and the issue I encounter is that there is no quick way to scroll through the items. I have to take my mouse cursor to the bottom of the screen where there is a little down arrow and then the bookmark list will start to scroll automatically, but the scroll speed is slow and I have no control over it. It would have been great if there was a scrollbar to quickly scroll through the items.
