A unique version of a POWr plugin (ex. Form Builder) is defined by its unique ID. Every new plugin you create will have its own unique ID number. You can see these IDs in POWr Shortcodes and HTML DIVs, like this:
|[powr-form-builder id=abcd1234]||<div class="powr-form-builder id="abcd1234"></div>|
When you purchase a POWr Single Premium Upgrade, you are upgrading only that unique version of that plugin.
You can use this unique version many times and on many different websites by pasting in the exact same POWr Shortcode or HTML DIV, or by using the SYNC option in the POWr Editor
You can change the Content or Design of a unique version whenever you like, and those changes will be applied to all other copies of that unique version.
