It would be nice to have a way to download a full list of all my bookmarks (+ info, tags / descriptions etc...), maybe as a .csv file?
In the case where raindrop.io stops working, or for some reason you decide to stop the project altogether, I don't want to lose my all of my bookmarks.
It would be nice to have a 'local' backup where I still have access to my bookmarks (even if it doesn't include everything - but definitely the URL's themself!).
