Re-realize scrollbar, simple design and floating display
This is an extension to hide the scroll bar of the webpage. After hiding, the function will be realized in other ways:
Click on the far right side of the webpage to quickly scroll to the top or bottom;
Click on the leftmost page to quickly turn the page.
Double-click can also mark the current browsing position and automatically generate a directory. Click to reach the content area, or press Ctrl to switch.
