Pickpocket Safari Extension lets you access, search, and open links from your Pocket (formerly Read It Later) account without needing to visit the site.
The extension has two basic modes of operation.
In list mode, clicking Pickpocket's toolbar button will open a popover containing a list of your Pocket links. Initially, the popover will list all of your unread links. You can search all your links by typing something in the search bar.
In tabs mode, when you click the toolbar button, Pickpocket will simply open all of your unread links in new tabs. (If you have more than 10 unread links, the extension will ask you to confirm opening them.)
In either mode, when you close an unread link's tab, Pickpocket will ask you whether you want to archive the link. If you say yes, it'll tell Pocket to mark the link as read, which moves the link from your queue to your archive. Optionally, you can set Pickpocket to always archive (or not archive) closed links without asking.
