     - scrolling in fullscreen is busted because no space outside of window
     - scrolling when clicking on scroller is busted
     - page up and down should also scroll and leave you in exactly same scroll
-    - something about mouse stuff is busted and it randomly does big selections and stuff like that
     - I think the way sublime text and we display line highlights is confusing with multiple cursors (line highlight can be confused with selection)
     - don't trim lines with cursor or selection on it
