KISS and just encrypt whole files or keep whole files in plaintext. So either 
that note application saves its file into the unencrypted tree or the 
encrypted one but mixing data inside files seems way more complex than really 
needed. It's not like notes are so big that the penalty of encrypting a few 
more than required would be that huge.
