Currently, Goodnotes allows locking individual documents with a passcode or Face ID, which is very useful for protecting sensitive notes. However, it would be even more helpful if entire folders could be locked at once.

This feature would:
• Save time by not having to lock each document individually
• Improve security for multiple sensitive notes
• Make organizing private or work-related content easier

It would be a great addition for users managing multiple documents and projects, enhancing both convenience and privacy.
