Is there a distraction-free writing mode like Vimroom(a plugin of Vim)?
I need a distraction-free writing mode very much, can Notepad++ do this?
About vimroom, please check http://www.rosipov.com/blog/distraction-free-writing-with-vimroom/
The closest you might find could be on the View menu. Try “full screen” and “post-it” modes, although neither give the distraction-free appearance of Vimroom that you are seeking. In the world of Notepad++, we look for things that get us most or some of the way to where we want to be when we can’t have it all. :-)
With a quick bit of plugin coding you can make it look something like this (note this is a full sized screen shot):
It would take a bit more work to make it a fully-fleshed-out and usable plugin though.
