I haven’t worked with Collabora before so I could be completely wrong but it looks like from the install doc that the “OK” string is what should be expected.

Is CODE the server backend to handle syncing and do you need to install a separate application that points to that server?

I know standard notes is like that.

You literally just said the two things I wished Kindle allowed me to do natively.

I hate the fact my Kindle store books will bundle by series, but my non-kindle books will not.
