Provide more granular access management (pure front-end implementation)
At present, only the notebook can be locked. If the lock document is not processed, the lock document will be abnormal
After installing the plug-in, right-click the notebook (not the document!) in the document tree. The pop-up menu will have a plug-in, and the secondary directory will have the option of 'Add password'
Press enter is confirm，click block is cancel !
After adding the password, left-click on the locked notebook and a dialog box will pop up
After unlocking, the right-click directory will become 'unencrypt' and 'Lock notebook', so you need to lock the notebook manually
