NoteItDown (Version: 1.2 as of this post) is a no-install, portable freeware Notepad alternative. Its features are basic and it is lightweight. It has the .rtf, rich text features such as changing text and (text and note) background color, adding or removing indent, aligning text and changing fonts.
Notes are saved in a tree structure and while the global search (File—>Find notes or Ctrl+F3) displays results in a separate window the search function above the note area searches the current note and displays matches incrementally as in a search as you type. The Insert menu features Date and Time, Date and Time options.
Links and email addresses are converted automatically and by default notes are saved automatically. On startup NoteItDown prompts the user to choose a location to save the notes or data, the three options available are the system application data, the program’s own or browse and pick any other folder. NoteItDown requires Microsoft .NET Framework 2.0.
