Manage and display links on a WordPress site. Plugin uses custom types, so exporting is very easy. 
To display links in a post or page use the following short tags:
[links cat=”name of category”]
[SHOWLINKS] for displaying all links
A simple option to export links per category is possible using the overview screen: 
Click “All Link Items” -> Click on the link Category you want to export -> [OPTIONAL, but recommended] Select “Title” to alphabetize your export list -> Select “Bulk actions” and chose the Export to xHTML -> Click “Apply” Now you can save you selection. Use pandoc.org to convert your selection to markdown or another format if needed.
This Plugin has a “broken link” check functionality. 
The Broken checks can take a while with a significant number of links. The screen stays blanc during progress. note: No progress bar is shown.
See https://www.bm-support.org/innovation-links/ for a live demo.
How does it work? 
This module makes use of Custom Post Types with non hierarchical catalogue option. So you can give links one or multiple tags. 
Tags works great for retrieving or exporting only certain types of links. 
If all tags for a link are deleted, the link still exist. This is default WP functionality. Since this plugin in built on using default wordpress hooks, 
exporting and importing links can be done used as with post or pages.

After WordPress 5.8 is released, infinite scrolling will be removed by default from the Media Library. See Trac ticket <a href="https://core.trac.wordpress.org/ticket/50105" rel="nofollow ugc">50105</a> for the releated changeset and ticket <a href="https://core.trac.wordpress.org/ticket/40330" rel="nofollow ugc">40330</a> for the historical context behind the decision.
This plugin, for the short term, is a global re-enabling of infinite scrolling in the Media Library for all users.
A potential future enhancement is to have a per-user setting, letting individual users decide what’s best for them.
