The interface is very pretty, much nicer than competitors like NoteTab. It has very nice features, such as customizing indents for different file types, unlimited undo, and tabbed display to allow multiple files in one window. The Lite version is free and is much better and has more features than other free versions of other programs, so I don't even see the point in getting the Pro version since the Lite version is so good. Overall excellent program, great replacement for Notepad.
