With Drafts-Keeper you can make a lot of password-protected and safely encrypted notebooks. For example, several books - for home, a few others - for office. Then you can work with all these books simultaneously: easy copying and moving notes and group of notes Between them, quickly finding necessary note or text.
Program is so small, so you can place it on one diskette with your notes and take it home to keep working on weekends.
It is so easy-to-understand, so you do not need any help guide.
If you are a programmer, you can use Drafts-Keeper to keep all your procedures and pieces of code and share them between your newly created projects by quickly copying/pasting.
You can make a separate NoteBook as your diary or collection of www-links, e-mails, etc.
Have fun!
