Move rarely accessed attachments offline
This is a feature request. Would it be possible for Zotero to keep track of how recently an item's stored attachments have been opened from within Zotero, and if it has been more than X time (say, a couple months) then the attachment is removed from local storage? This would help to free space on local drives. I find that when I have to download an attachment that is not yet local it is rather fast, so I don't think it creates any substantive inconvenience for users who typically expect to be online.
