This plugin adds the ‘Like’ button and ‘Who Likes’ list to:
<ul>
<li>WordPress posts and comments</li>
<li>BuddyPress activities and comments</li>
<li>BBPress posts</li>
</ul>
It allows for registered users to like the items. And it shows for both registered and unregistered users the existing likes.
The components to show the likes to can be configured on the settings page. For example, the likes can be disabled for WordPress comments.
Likes are saved in the internal WordPress and BuddyPress meta tables. No separate tables are created.
The plugin cleans all its data on uninstallation (but not on deactivation).

Step pay allows customers to pay their orders by installments, with 3 payments in 3 months. 
Customers will be redirected to the Splittypay platform to complete the payment: from the platform customers can: 
* Add their credit cards or bank accounts to pay 
* Pay by installments 
* Monitor the payment in real time
Merchants need to register to the Splittypay service to access the Step functionality as the plugin requires an API key to work properly. 
A merchant, to get an API key, needs to fulfill four simple steps: 
* Connect (or create from scratch) their Stripe account 
* Fill some basic information about the business 
* Upload a logo 
* Customize the cart duration on the Splittypay platform
The Step pay plugin can work both in sandbox and live mode. Merchants can switch between the environments from the settings panel 
(different API keys are required for the sandbox and live environments).
