When you long-press on a note in the Note app (latest firmware with build no. 2018-07-03...), you get the following options in the popup menu: Delete, Move, Rename, Import, About.
Does anyone know what "Import" does? I seemingly doesn't do anything, and there is no mention of it in the manual (why would a manual actually describe the operation of the included sofware

)
In other apps I have used, "Export" is usually associated with single files and "Import" is available on a higher level to import files from other locations into the app.
