Add a scroll bar that is always displayed for the mobile terminal.

When you play a game on the Windows computer, you will see an always-displayed scroll bar on the far right or the far left, so that players can scroll the page quickly. I think you should also add an always-displayed scroll bar on the mobile terminal (mobile phone). When you hold down the scroll bar, you can scroll the page faster by moving it up and down, so that you can find options quickly. You can add a button to turn on or off the always-displayed scroll bar.
