Since the update to Zotero 7, the automatic PDF preview in the lower part of the right-hand pane no longer appears when selecting an item that contains a PDF attachment. Previously, Zotero would show a preview of the first page of the attached PDF immediately upon selecting the parent item in the middle pane — which was extremely helpful for quickly identifying and reviewing documents.

Now, the preview is only displayed after clicking directly on the PDF attachment itself. While I understand this may be an intentional change related to the new user interface, it feels like a step backwards in terms of usability and workflow speed.

I would like to kindly ask the developers to consider reintroducing the previous behavior, or at least offering it as an optional setting. Judging by other comments in the community, I am not the only one who found this feature very useful.

Thank you for your consideration and all the great work on Zotero.
