Attaching Files to Notes
By default (and for now), all notes are in the
.textbundle format, which means you can include arbitrary file attachments with each note.
I have a branch that supports displaying attached files inline in your note, but that's not ready for testing yet.
For now, you can drag and drop files from other apps and the Finder into the Attachments list in the Info panel and then preview them or export them when you need them again.
