allow scrolling down further than the last line
When I code I like to work at the top of the document, this means that I sometimes (/often) have to add a lot lines below what I'm working on if I'm at the bottom of the document.
I have friends who use VS and they are able to scroll down further than the last line, it would be cool with something similar in XS.

This would be especially useful on a portrait monitor!
