petitnuage

This widget displays titles and links to the latest posts of a custom list of third party RSS feeds. It is useful for people who want to follow third party feeds updates on their own blog. It is also useful for blog networks where each blog can promote the latest posts of other blogs of the network.
Features list:
<ul>
<li>Customizable title.</li>
<li>Customizable introduction displayed before the recently updated feeds list.</li>
<li>Customizable number of maximum posts displayed from the same source.</li>
<li>Customizable number of maximum posts displayed in total.</li>
<li>Localized economy and market share news feeds supplied by default for immediate use (many thanks to <a href="http://www.labourseenaction.fr/" title="La bourse en action" rel="nofollow ugc">Bourse en ligne</a> for both English and French original news feeds).</li>
</ul>
Languages supported:
<ul>
<li>English</li>
<li>French</li>
</ul>
The plugin uses WordPress standard localization functions for localization. So, adding support for new languages (including the list of default RSS feeds, separated by “!”) should be straightforward.

Modifies RSS feeds so that they include pages and not just posts. Deactivating the plugin restores RSS feeds to their default state.
Including pages in your feed is particularly useful if you’re using WordPress as a CMS where pages represent a good portion of your content.
The <a href="https://infolific.com/technology/software-worth-using/include-pages-in-wordpress-rss-feeds/#pro-version" rel="nofollow ugc">pro version</a> (a lifetime license is less than $15) also allows you to:
<ol>
<li>Specify that ONLY pages are included in the feeds i.e. no posts.</li>
<li>Exclude/include posts and pages by ID.</li>
<li>Add custom post types such as WooCommerce products or Avada portfolios.</li>
</ol>

RSS Includes Pages

Some people say this plugin is useless, but they don't seem to be reading the description. If you want pages to be added to your existing feeds, this plugin will do that. No settings or configuration. Just activate and go.
Some additional features are in the pro version, but 30,000+ users find the free version useful enough to keep it active. You can't argue with the numbers! :-)



Adds Pages To Feeds Just Like It Says

Completely useless plugin. Only includes posts and pages into the RSS feed. For custom post types you have to pay $10. If you plan to make money with your plugins, please say so in the description so people don't waste their time.
