Currently, I can specifiy, in % of page length, when the scroll to top anchor should be displayed. This makes not really any sense.
Lets say I have a page which is 1.000vh long (10 times the viewport hight). A setting of 75% requires that the visitor scrolls down 8 pages before the anchor shows.
On another page which is only 200vh long (2 viewport heights = 2 pages), the anchor will show immediately after I started to scroll.
What would make more sense from a user perspective is a setting in 100vh units. A setting of 3 would mean: If I scrolled down more than 3 pages, show the anchor to help me go back up.
If you think this makes sense, then I would like to post this as a feature request.
