How to view all the list of Discount Rules

To view the list of all discount rules at once, click on the Discount Rules for Checkout link that is present on the top of your plugin dashboard. This will render a list of all rules in front of you.

Also, you can sort the rules by ‘status’, ‘name’ and ‘amount’ in order to easily find out the desired rules. For example, sorting by status will group all enabled rules together and disabled rules in one place. Similarly, if you’ll arrange the rules by name, you will be able to find out any rule without troubles. 
Clicking on the name of discount rules for checkout from this list will open the rule settings (or edit) page, from where you can change configurations.
