Adds three widgets – “Text/List”, “Text/List (If Logged In)” and “Text/List (Not Logged In)”. These can be used much like the normal Text widget, except two of them only display if the condition is met.
Potential Uses: 
* Add a link to a Register page, along with some text promoting registration (for example on a site with the bbPress plugin) 
* Display adverts to users who are not logged in 
* Display useful links to users who are logged in. 
* Display a nice list to everyone.
Because the widgets are separate, you can have the logged-in widget in a different place to a logged-out widget. You don’t even have to have pairs of widgets.
Unlike the normal Text widget which just has a toggle for paragraph on/off, this widget has four display options:
<ul>
<li>No formatting</li>
<li>Add paragraphs</li>
<li>Bullet list (ul)</li>
<li>Numbered list (ol)</li>
</ul>
The list options are useful if you are adding a number of links – simply add each one on a new line and they’ll be turned into a bullet. Please note that this plugin adds no CSS. Often themes style the lists within a widget to make menus look nice, so your theme may (for example) prevent numbers from showing. See FAQ.
You may find that the Text/List widget is useful even without the logged-in / logged-out conditional.

Logged In Conditional Text Widget

Adds text/list widgets - one only shows if user is logged in, and the other only shows if a user is not logged in. A third shows regardless.

Have you ever used WordPress’ new block editor Gutenberg and wished for a way to influence, when and to whom blocks are shown? We’ve been in this situation, that’s why we came up with Block Control. This nifty little plugin allows you to control, whether a block should be displayed under certain circumstances or not. And that’s of course true for both WordPress’ default blocks and blocks added by third-party plugins.
You can hide blocks based on:
<ul>
<li>Device types (desktop, mobile, screen reader)</li>
<li>Login status</li>
<li>Date (start and end date)</li>
<li>User roles</li>
<li>Page types</li>
<li>Posts of the current post type</li>
<li>Page number in numbered pages (in archives and search results)</li>
</ul>
Additionally, you can set an inline formatting to display certain text only for screen readers.

Block Control

I've used this plugins on two websites now. It works just great. The visibility option for different devices is very useful.

It works just smoothly

Lovely helper plugin lets you select, if you need to be logged in to see a block in a post or page and whether it should be hidden on certain devices.

Currently the plugin description may be a little vague ("it does what?") but the plugin works right out of the box and may be for many a smart solution for a simple task. 

Well done, Matthias and Simon. 👏🏻

Nice little helper plugin

Block Control allows you to take control of all the blocks on your website. Tailor a unique experience for your visitors.
