This WordPress plugin (widget) will be shown when visitors are viewing a single post, category page or both. Otherwise, it wont be there at all. 
The widget contains a list of post titles from the same category(s) the visitor is viewing the post from, so the visitor is able to swiftly change posts by clicking on the titles shown. 
Posts published in multiple categories are taken care of just fine. I’ve introduced a new feature in version 1.6 which gives you the possibility to show all the categories the post has been published in or the category where the visitor has been spotted the last time(uses cookie).
The widget can be controlled with the following widget options:
<ul>
<li>Title (before the category name(s))</li>
<li>Exclude category(s) by ID</li>
<li>Exclude categories on: Single, Category, Both, None</li>
<li>Sticky posts on top: Yes | No</li>
<li>Show posts from year: a specific year or all years</li>
<li>Show widget on: categories | single posts | both</li>
<li>Show category title(s): Yes | No</li>
<li>Post has multiple categories – what now: Show all categories | Show the last category viewed</li>
<li>Show how many posts</li>
<li>Single posts view – Order: DESC | ASC</li>
<li>Single post view – Orderby: Author | Category | Date | ID | Random</li>
<li>Category view – Order:?DESC | ASC</li>
<li>Category view – Orderby: Author | Category | Date | ID | Random</li>
<li>Remove/Keep child categories</li>
</ul>

WordPress Widgets are really great to keep the elements on your site modular and reusable. They have the option to have their title in them if you want to. However, this field is optional, and you leave it empty for those cases you don’t wish to display a title in the frontend. What about those times you have to stack many widgets into a sidebar without titles.
WordPress by default only includes the widget type as the name of the widget in the title bar when the title is not included, making it impossible to have an accurate reference of the function of that specific unit. That is where this plugin comes in handy.
This plugin will create an extra field on every widget in the Appearance -> Widgets area (not available in the Customizer) named “Widget title” that will allow you to have a custom title for that Widget. You can just leave this field blank when you want the default titles from WordPress.
Enjoy!

Custom Admin Widget Titles

This plugin allows you to input nice looking and descriptive widget titles in your admin widget area.
