When a WooCommerce product is on sale, a tag is placed on top of the Product Thumbnails. The default label for this tag is “Sale!”. 
This plugin allows you to customize the label and can even insert the price difference or percent difference. Examples:
<ul>
<li>Save 20%</li>
<li>20% off!</li>
<li>Save $5.00</li>
<li>$5.00 off!</li>
</ul>

Woocommerce Custom Sale Tag

Customize the sale tag that appears on WooCommerce product thumbnails when a product sale price is set lower than the retail price.

This Plugin allows you to Add personal Notes, comments, memo to each of the Plugins. 
You can change or delete any Note at any time. 
Notes are available to anyone who has access to the Plugins page.
Here are some reasons why “Plugin Notes Label” is needed and useful: 
– Over time, sometimes you forget exactly why this or that Plugin was installed. 
– Some Plugins have to be modified (although this is not correct), and their updating requires special attention. That is, you need to remind yourself and others that you cannot update such a Plugin without careful preparation. 
– Sometimes you expect a specific new promised functionality from a certain Plugin, and up to this point, all intermediate updates are not particularly important. 
– Anyone who administers WordPress can remember a few more similar reasons. ))
