open 2 text files side-by-side using notepad++

Notepad++ has been mentioned here before, but one feature not talked about is the ability to open text file side-by-side.

This is great feature now that every bod has wide screen displays and notebooks.  I'm considering buying notebook with 1600x900 display, possibly Samsung Series 9 or Lenovo X1 Carbon, this feature would be very useful...or I can just use emacs for Windows, I guess.  However, I found that synchronize scrolling in Notepad++ is very nice.  Consider that using track pad on the notebooks is not that precise, having two related text to scroll at the same time can save lots of effort and possibly wrist strain.
