|PLUGIN: Child Theme Configurator
This is one of my favorite plugins. It has saved me lots of time and it does a few things better than I can.
If you're not doing any coding for your site then you won't need this. But if your about to spin up a new WP site and you need lots of customizations that you can't get from your theme or plugins then you will need to create a Child Theme.
A Child Theme is where all site code customizations must be made. And to get that process started the go-to workhorse is the Child Theme Configurator.
Once this plugin does its thing its work is done. It can be deactivated and uninstalled.
