Is the idea to get the embedded metadata inside the HTML files to reflect on the file itself? I've been Googling but not found anything that'll do the trick. I look forward to your solution, though, if you ever get round to it.
The Evernote Apocalypse has come for me, unfortunately. I still intend on using it for a few notes here and there, but by and large its incessant problems and lack of improvements have kicked me out. Making the migration to Google Drive, however, is gonna be a sad affair if all my 1000s of notes were 'created yesterday'.
