Hi Seth;

Any chance you'd consider adding Proton Drive as a cloud library option? It's one of the only features that are stopping me from abandoning Calibre Sync altogether.

Cheers.

I'll look into it.

Thank you.

I looked in to it. but Proton’s developer tools do not yet support production use by third-party apps like LibriLink.

EDIT: It's reported they are working on adding 3rd party support.
Let me look at it some more, if Calibre Sync got it to work, there's a way. I'm wondering how future proof it might be, if Proton has released a full solution yet.

Strange. It works in Calibre Sync.
