I have to agree, this feature would help me a lot. On some pages I have like 10 accounts (for different pruposes) and they are just random numbers sometimes - then it would be awesome to add a note.
Yes, please. As someone who has used LastPass, a secure note feature or even a description text box for each entry would be life-saving. Having to have a different solution for securing notes or more details related to the login/pass is a bit of a pain so this would be an excellent feature!
A notes feature would also allow the addition of answers to “security questions.” Since that is still a thing, having to store those separately from the secure password is a problem.
