I know there is nothing as yet as to what you (the parent) are asking for.

Yellow Notes is just for jotting, it wont even store in multiple files. Essentially you want a file manager applet.

But on a different note - Liqbase does allow you to handwrite notes and then it stores them (within liqbase interface) as a list of "files" sorted by date. So you can scroll down the list of notes by dates and select one and open it again.

But again this is all part of the liqbase application itself. You need to start liqbase to be able to see the stored notes.
