Alternative scroll bar
I noticed that on some websites the designers can change the scrollbar. I was wondering whether such a change should be introduced also to this extension, as the current default windows scrollbar is rather huge and obstructing:
An alternative might be something like this, i.e. much thinner and fading away if the mouse is not above...
Please note that the screenshots of both scrollbars were made on the same machine running Windows 10, MS Edge, so it should be not app-dependent.
