From Aaron Spuler:
Notebook is a text editor that can be used to take simple notes, or as a replacement for Microsoft's Notepad application. When not in use, Notebook resides in the system tray. Notebook will automatically save the text you have written upon exit and restore it when restarted. Notebook incorporates all the standard features expected from a text editor, plus a few extras. Features include: open, save, & print capability for text files; spell checker; global hotkey assignment; transparency; ability to stay on top of other windows; ability to load when Windows starts; live update over the Internet.
