Hey, great questions: - We do support markdown as you're typing (they're turned into the appropriate element as you type). Currently, pasting markdown has some bugs, but we definitely intend to fix those soon. - Right now, you export a single note as a PDF. I figure you're asking, "can I export all my notes and take them with me". The answer to that is currently no, but we fully intend to support that. And if you need that in the meantime, we'll definitely do a one-time export for you. - Yes, you can create checkboxes in markdown, and we also have simple checklists ala Google Keep as objects. However, we don't have complex todo features such as due dates, assignees, dependencies, etc.
