@www.rzr.online.fr: I use it on my n950 a lot. It is a great basic text editor, very fast, stable and gets the job done easily!
What I can suggest is: *when loading a text file and and navigating through the folders I always forget which color means a text file. Maybe changing the icon for folders.
*adding a scroll bar to the text field (to know where I currently am in the file and how big the file is).
