Great Program I have just started to use

It is called Dark Room. Basically, it is a minimal text writing program. It go full screen and it is just me, the keyboard and the screen. NO DISTRACTIONS. I find that my notetaking in class and productivity outside of class as very much improved using it.
Here is a screenshot:
