To save tabs to Pinboard, create a file with extension.plist in the App's "Library" directory. The.plist file will contain an array of strings and dictionaries, which are just like plain text files but are actually XML.

The first element of this XML is the title. You can name it whatever you want, but it needs to be unique for each category of the extension. Each array element contains a list of strings that will be added to the Pinboard account for every tab that you save to this category. The first element is a string, the second is a dictionary containing the data for that particular item.
