Add option to show scrollbar when mouse near the edge

[fastaddons]

This is similar to mobile devices where scrollbar is hidden and is visible only while scrolling.
Here it would be hidden unless user places cursor near the edge (where scrollbar should be).

However this may be a challenge here as un-hiding scrollbar can change page layout.

What if instead of hiding the scroll bar it just became transparent, that way it would be easier to implement.

This other add-on shows the possibility of using transparency, so I imagine it will be viable.

And this other add-on already has the function of detecting the mouse when it lands on the scroll bar.

Great idea with the transparency!
But I'm not so sure about detecting the mouse over the scrollbar, but I should be able to detect it near it.
Anyway, I'm bit busy these days/weeks. It may take a while for me to get to this.
