Bigger Scroll Bars

Would really like to have bigger scroll bars that fingers on a touch screen can actually use.

You can use touch scroll you don’t have to use scroll bars. Touch and hold anywhere then swipe up or down.

Yes of course but often you end up selecting another menu item on the process. Not ideal.

We use ELO touchscreens

Yep, and when using the HTML viewer widget our ELO screen often selected text rather than scrolling the web page vertically, so using a scroll bar could be handy.
