We have just release new experimental feature available to all our Premium users.
Thanks to Import from file you can now import your note content from most popular document formats like .doc(x) (MS Word), .odt (Libre/Open Office), .txt, .rtf and .html. This will import not only the text with formatting, but also images.
In order to import external document, in right panel open "Import from file" tab, then select the file you want to import from and click Import. Your current note content will be replaced.
Premium users can also use other features like Version history or Encrypted notes.
