If you want to create a list-type post with, say, 21 links to something, you can use this plugin to change those links into separate sections. And the most important – your visitors could vote (+1/-1) for each of those sections separately.
This way you would see, which section/link is the most popular among your readers.
Current features:
<ul>
<li>Dividing posts into sections with shortcode [psv-section]</li>
<li>Voting for each section, with result of voting available immediately in the post</li>
</ul>

Post Section Voting

Divide posts into sections and implement voting for each of them. Great for list-type posts.

<h4>Reset Customizer</h4>
This plugin lets you reset a section of customizer settings without losing settings in other sections. Settings are not saved until you click “Publish” in the customizer.
Reset buttons are injected into each section of your customizer. The settings in a section are cleared and the preview window is refreshed when the reset button is pressed.
Entire sets of customizer modifications for a particular theme can be downloaded (backup as JSON data) and / or deleted.
You can then choose to restore a set of customizer modifications to the active theme. This can be useful if you want to migrate theme modifications from a child theme to a parent theme.
View active theme mods and choose to delete individual mods.

Adds a reset button to each section in the customizer and easily backup / restore / migrate customizer settings
