A custom plugin that will display dynamic text from the values you enter in special custom fields on a post inside of a WordPress Widget.
Add any text you want as the value of the ‘posty’ custom field and it will show up in this widget. Title the widget with the ‘posty-title’ custom field. It only works on single posts.

List post from a specific category with options like date format, link text, order and more. Locus is a very simple plugin for display content in diferrent ways:
<ul>
<li>Display a single post, page or any available post type.</li>
<li>Display full content or the excerpt, or both!</li>
<li>Category descriptions are visible by default, if any.</li>
<li>Configure date format, link text or hide them all.</li>
<li>Use styles for every block, (refer the stylesheet in <code>locus/control/locus-style.css</code>)</li>
<li>Set display post orders, such random, by date, by author, comment count (popularity) etc</li>
<li>Display thumbnails, if available</li>
<li>Easy to use: you don’t have to learn to use it</li>
<li>Settings per widget, so you can have different widgets.</li>
</ul>
