Not really a problem… just to be sure I’m not overlooking anything: Even if I select all documents, there is no way to change the metadata 
for all documents at once. Is that correct? Thanks.
Perhaps I should add that it is a drop-down menu.
Only the metadata of previewed/opened documents can be changed currently.
Sorry, I don’t know what that means. Could you please explain that in more detail?
Ah, I see, select the documents and change the metadata it in the inspector.
That’s fine for me, thank you.
