Scrolling using the space bar:
Currently when you get to the end of a page, the screen stops at the bottom of the page.
This means that one has already read the text at the top of the page (unless page length is an exact multiple of the screen height).
This is distracting, because it's not easy to find where the unread text starts.
I would like to see white (or grey) space added to the bottom of the web page so that the page always starts with unread text.
I see this being the default way of presenting a web page when scrolling using the spacebar.
