I often find myself saving journal article references by clicking the icon in the address bar, and then subsequently attaching images and pdfs to it in a two step process: first using the "Save Link As Zotero Snapshot" and then drag-and-dropping the snapshot in the Zotero window to the recently-saved article reference.

I was thinking that it might be helpful, in addition to the "Save Link As Zotero Snapshot" right-click option in the browser, to also have a "Save Link as Zotero Attachment", which would automatically save the snapshot and attach it to the last-saved entry. Don't know the feasibility of this, but it seems like it would be broadly useful.
