That works with any editor (nothing prevents opening multiple MS-DOS 
windows - I usually have about 20 of those open). The real problem is that 
one needs a massive screen to really have enough room - I once calculated 
that I'd need a 52" screen to show all of the source code that I need to see 
to work on the compiler side-by-side. And I had better vision then; I 
probably couldn't even see the edges of such a screen today (it would have 
to wrap around my head at an even 18-24" distance!!)

One of the reasons I never use GPS is because it comes up in a font that is 
rugged and too hard to read on my computer. Making it bigger fixes that, but 
then I'd need a lot larger screen than the 24" one I have today.

Moral: these things help, but not that significantly.
