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.
