It would be great if we can rather add this to the vue.js based frontend, but maybe that is something where @elzody can help moving that over

Oh, I was just tracing how the zotero API key setting does this, and this way seemed to be the way it works. Maybe move the zotero API key handling to the vue.js based frontend, and then I'm happy to do the same for these settings as well? Thanks.

Ok, also wouldn't consider this a blocker then especially since zotero is also still there in the legacy part. We can migrate them together afterwards as well
