Thank you very much! Very good hint

Can I ask two more questions?
1) Will it cause any trouble to have a lot of custom columns or is it fine? Assuming something like 10 users * 10 special columns per user for reading progress, first read, last read, etc. = ~100 custom columns.
2) I read that it is not possible to create custom columns using the calibredb command with a content server as the database needs to refresh, is this still valid? I also didn't find any command in the JSON API. I am asking as this is the only action that is missing to use it for this "generic" use-case like this.

Best regards
