Thumbs up. I would just add the encryption filter, like gpg to yourself or within the editor automatic decryption and encryption.

You can also add your own file type if necessary.

Good point and easy enough to add, although it does not fit my use case: I want the files to be readable on mobile, plus I only put non-confidential, to-be-public, or already public data in there.
