PHP Depcreated functions & Warnings

In my local dev environment, I work with WP_DEBUG on and noticed this plugin has a couple issues that cause pages of PHP warnings to be displayed before any content is rendered. I use PHP 7.2 which is when create_function depcreation warning came up. Any chance you could push some updates to keep a clean dev environment?

Thanks!
