You can use customisable templates to export content in formats of your choice.
Everywhere you find the Cite buttons you can trigger the copy process.
Copy pages with their notes
This will take as a copy context the page and its notes
Copy individual annotations
This will take as a copy context only the single note
Copy search results
This will take all the pages and their annotations that match a certain search query.
You'll find the icon next to the search box in the dashboard
Creating a template
You can piece together an template for your export by clicking on "Â New" or the edit button.
On the bottom there are drag & drop variables that you can pull into the template. Their functionality is explained by hovering over them.
