Since 5 years ago, a large numbers of users have suggest to Add a very very simple Function: Password Protection. 1. We need PASSWORD to Protect personal notebook! NOT encrypt the Note or NoteBook! Just use password to prevent accidentally open! (Don't mention there is encrypt text function in your product. That's not what we are talking about now.) 2. Why? We Stored some personal stuff in it. When we use the function called ---Present notes, We‘d like to hide personal Notebook or use password to protect it! Imagine it : When you guys are presenting A Note, you accidentally click on the notebook which stored some personal stuff , it's a disaster！ I'm a Premuim client, and the reason why I purchased premium account because I was looking forward to enjoying a very good software and service. At least I think I can use such basic function like password protection just as other software.
