Export and import to/from Markdown-formatted plaintext
Export/import to/from plaintext with basic Markdown formatting would be really nice. With "basic" I mean: no text styles, no checkboxes, just the sibling/child structure (and maybe support for notes).
This way we could do major editing with any text editor on the Mac/PC.
I agree... I use CFO for my to do list... It would be great to import and export to the editor without all the extras.
