This is a basic plugin to show BTC exchange rates from blockchain.info public API, as a sidebar widget on your wordpress site. No configuration options are available at this time, but maybe added in future, including which exchange rates to show and other minor changes. Plugin uses native WP caching, to minimize server load improve user experience.
