Display feed for category in page, use simplepie and import feed 
from external site and display it in category page.
This add new fields to category: the url of feed and the title 
that will appear in the widget.
It uses simplepie class that came with wordpress distribution.
<h3>Upgrade</h3>
I am experiencing some problem, deactivate and reactivate the module 
should fix those. Be carefull, just make a backup of table data 
(prefix_category_ext_feed), deactivate plugin, then reactivate. 
Thus if data about feed is not available anymore, just replace 
the table.

WPKube

The plugin restores the <code>Title</code> field (that was removed from WordPress 4.2) in the insert link popup box and adds a new <code>Add rel="nofollow" to link</code> checkbox to it.
Gutengerg (Block Editor) Note: At the moment it’s not possible to add the functionality to Gutenberg, it’s a different system from the classic editor and it does not have a hook/filter which allows adding custom settings. As soon as it becomes possible to add the functionality to Gutenberg we will update the plugin.

Title and Nofollow For Links (Classic Editor)

I just installed this on WP 4.9, and it works like a charm. I ended up adding HTML Class manipulation as well, by coping the code in the JS file that added the title field.

Works Well

works with wp 5.2.1

Helpful tool

The plugin adds a title and a rel="nofollow" checkbox to the insert link popup box. Only for Classic Editor, NOT Block Editor.
