Tim here again. Speaking of clipboards and security, that's the
one aspect I've had to take extra care with. Sometimes my password
manager will put a password or credit-card number on my clipboard
and clipit will dutifully note it and keep it in the history. So
I have to be extra careful to go back and edit the clipit history
to remove either the particular sensitive information, or (more
lazily) just clear the entire clipit history.
Just a precaution to keep in mind as you venture forth (smile)
