Imports are a powerful feature in Plucky configurations. This page shows a couple examples of how they might be used.
Example 1: Susan's books
Susan likes to research books on the Internet. She also uses Plucky. Over time, Susan has added to her Pluckeye configuration a large number of links to children's books on goodreads.com that she thinks would be useful to other Plucky users who also like children's books. To do this, she creates a new configuration of type "allowed urls", and names it "Susan's approved children's books". She then edits the configuration, copying in all the urls she has accumulated over her Plucky history, and saves the configuration. After saving it, she clicks "Share" and "Publish" to share the configuration with all Plucky users.
Peter, another Plucky user, sees Susan's configuration in the list of public configurations. Peter views the configuration and clicks the import button. When prompted for which configuration to add it to, he selects his one and only configuration. After his delay elapses, Peter then inherits Susan's list of approved books.
Later, Susan adds more books to her public configuration. These changes automatically propagate to Peter's computer.
If Peter decides he no longer wants to use Susan's list, he can remove the import rule for "Susan's approved children's books".
Example 2: A Reddit Subreddit blacklist
u/cocucu on reddit has written a program that crawls reddit and identifies not-safe-for-work (NSFW) subreddits. u/cocucu takes the output of his script and creates a new configuration of type "blocked urls". u/cocucu then makes public the configuration so that other Plucky users may import it in their configurations.
