This plugin allows you to pass content to any sidebar from the page without using userdefined fields. Therefore it is possible to use the WYSIWIG-editor of your choice.
How it works: 
This plugin comes with a new enclosing shortcode [sidebar_content][/sidebar_content] where you can place any content, you want to have displayed in the sidebar. You will be able to use other shortcodes within this shortcode to use galleries, videos or any other stuff in the sidebar of your choice.
Additionally there will be a new widget which you can insert into the sidebar you want to have the content displayed. 
If you would like to pass content to an existing sidebar, there is another possibility using the [insert_sidebar_content] shortcode in any place you want. You are able to pass an id and/or a class to that content, to be able to style it with css as you like. This happens by simply adding: 
[insert_sidebar_content id=”yourID” class=”yourClass”] to the shortcode. You can of course use just one or none of them. If you do not specify any custom class or id, there will be a standard class and id called “insert_scfs” applied to the content, wrapped in a div.

List the most recent posts with post titles, thumbnails, excerpts, authors, categories, dates and more!
Although the plugin is built only for widget areas users reported that it works in Elementor and works in Oxygen. Whether it runs in other page builders is unknown. Please let me know in which page builder you were able to use the plugin successfully.
The plugin does not collect any personal data, so it is ready for EU General Data Protection Regulation (GDPR) compliance.
<h4>Lightweight, simple and effective</h4>
No huge widget with hundreds of options. This plugin is based on the well-known WordPress default widget ‘Recent Posts’ and extended to display more information about the posts like e.g. thumbnails, excerpts and assigned categories. And it provides more options to build custom-taylored posts lists.
The thumbnails will be built from the featured image of a post or of the first image in the post content. If there is neither a featured image nor a content image then you can define a default thumbnail.
You can set the width and height of the thumbnails in the list. The thumbnails appear left-aligned to the post titles in left-to-right languages. In right-to-left languages they appear right-aligned.
<h4>Custom Post Type</h4>
If you want to list custom post types with the featured image, please check out our plugin <a href="https://www.kybernetik-services.com/shop/wordpress/plugin/ultimate-post-list-pro/?utm_source=wordpress_org&utm_medium=plugin&utm_campaign=recent-post-widgets-with-thumbnail&utm_content=readme" rel="nofollow ugc">Ultimate Post List Pro</a>.
