From Nikola Dachev:
nPad2 Source Viewer/Editor is designed to be used with small or very large projects in mind where an internal project manager is inappropriate and integration with file manager is crucial. nPad2 is also suitable to be used as notepad replacement. nPad2 works well with large text files too. Likely usage scenarios could be: source viewer for huge projects, editor for small projects, complimentary editor for quick editions, notepad replacement, and SQL editor.
