Currently the defaul for the Scroll To Top button is the left hand side of the screen as per the attached screenshot.
Is there a setting where this can be switched to the right hand side of the screen?
My normal single hand usage of a mobile device is intuitively that the Scroll To Top button should be on the right hand side of the screen. Would make it much easier to use the thumb to press this if it was located here.
The bottom right corner is reserved for other buttons, (you might not use), which is why it's placed on the left side.
You can use this custom code in the Settings / Tiger / Advanced / Custom code / CSS box:
