What is "notetab"

NoteTab is a freeware/commercial, multi-file, full-screen text editor for MS Windows. It was developed by Eric Fookes of Fookes Software, Switzerland. The program's name refers to the fact that it was one of the earliest text-editors capable of editing several open documents (or files) on different tabs ( tabbed document interface). The first version, known as Mini NoteTab, was released in 1995 ; version 5 was released in 2006, version 5.7 in 2008, version 6 on May 4, 2009, ver 7.0 in Mar 2012, 7.1 in Oct 2012.
