This is a “set it and forget it” widget which allows you to display shelves and reading progress from your Goodreads profile. You can add multiple widgets and configure them individually to show multiple shelves.
Some configuration options:
<ul>
<li>Large/small cover images</li>
<li>Message to display if shelf is empty</li>
<li>Sort books by reading progress, date updated, shelf position, author, title, etc.</li>
<li>Number of books to display</li>
<li>Display your rating</li>
<li>Show first line of your Goodreads review (intended for quick notes such as “reading this together with Alice”, “recommended by Bob”, links to reviews, or whatever else strikes you fancy)</li>
<li>Show reading progress bar, progress text (no bar) or don’t show progress at all</li>
<li>Display time since last update (e.g. “2 days ago”)</li>
<li>Custom strings for time since last update (e.g. for quick and easy translating, or to change “2 days ago” to “2 floobargles since last update”)</li>
</ul>
Almost all HTML elements have dedicated CSS classes to allow you to easily override the style. The widget looks OK on the most popular WordPress themes.
Requires PHP 5.4 or later (PHP 7 supported).
