In the meantime, is there any way to get the votes information using a quick hack in the browser's dev console?

I could write a small export, but yes, you can probably also do this using the console though it may take some times

this part could be rewritten to get all the vote item and all the votes on all sessions : https://github.com/HugoGresse/open-feedback/commit/17ac4b2715c7b28bee71f1753fc4c81078487f0e#diff-ffd57d13d82bfa50b65b9f005d3d413d11690d2f532c7ae3373ae2f10101e64cR15

Thanks for the hint, I will start from there!
