Component
OI Notepad is a full-featured open source note taking application. With it you tag, search and send your notes in addition to basic functionality such as creating, deleting and editing notes. Advanced features like encryption, import/export and voice memos are all available through extensions. All this functionality is brought together in a simplistic and efficient layout, customizable through variety of themes.
Proposal
My suggestion is to have a individual note password to secure private notes.
Mockups/Examples
Before
After
The photo below is edited version with the lock feature above, when the user want to lock the note he/she is typing the user will just click the lock botton.
Benefit:
The importance of having this feature is that the user can set private note locks for a specific notes. It will also make the application more enhance and updated.
