Adding "attachments" like that, the way Boostnote also does it, is not portable nor ergonomic, since you need the full path to the file in question or you need to upload it somewhere.
Markdown already handles 'attachments' via tag for image or HTML anchor for other file types. Prettify via CSS.
Global search and replace indeed needs an extra effort. If faced with such a need, I'd just use any of active IDEs already installed, well, Atom should do.
